Frequently Asked Questions for Rotary Vacuum Pump Series
The operating principle is the most notable characteristic of PISCO Rotary Vacuum Pump.
It utilizes PISCO's proprietary "rotary system" that is distinct from a vane, diaphragm or rolling piston system. This operating principle brings various benefits, significantly contributing to energy saving.
What is the rotary system?
To put it simply, the rotary system creates vacuum air by repeating eccentric rotations of specially shaped rotors.
Check the following video on the operating principle.
"The operating principle of Rotary Vacuum Pump" (in Japanese only)
Furthermore, the structure of Rotary Vacuum Pump has the following characteristics.
It has a fixed micro-clearance between the rotor and the cylinder.
This brings a largely non-contacting structure and minimal sliding areas.
Unlike a vane pump, wear particles will not be scattered.
Magnet coupling is employed to transmit rotational power between the motor and the pump.
Without seals sliding on the rotating shaft, heat will not be generated, and no maintenance is required.
It minimizes misalignment of the motor shaft, contributing to a longer service life of the motor.
It delivers rotational balance.
Low operational noise and vibration has been achieved with a thorough balancing design for the rotating part.
These are just a few features of PISCO Rotary Vacuum Pump, and we are receiving inquiries for applications including adsorption conveyance and vacuum packing system from a wide range of customers.
Please see our catalog for more details.
It is possible that the thermal protector was activated due to the motor’s excessive heat. Please check for any unusual odor or smoke. Please be careful not to burn your hand when touching the pump as it may be extremely hot.
Once the main unit has cooled down, turn on the thermal protector* and energize it again to see if it starts working.
*) RPV064 (120ℓ Low vacuum type) features a self-restoring circuit that automatically resumes operation when the temperature drops to the resumption temperature.
In the specification we provide, it is stated that the operational gas (intake gas) must not be corrosive or explosive.
Please contact PISCO sales office in your region for chemical-proof properties.
*) Users need to evaluate the gases outside the product specification range before making a decision on their usage.
DO NOT inhale flammable and explosive gases. Also, NEVER use Rotary Vacuum Pump in flammable and explosive atmospheres where there is a risk of ignition. It may result in a gas explosion or fire.
*) NEVER inhale volatile alcohol components and the likes as well.
In the specification we provide, it is stated that the operational gas (intake gas) must not be corrosive or explosive.
The intake of high-temperature steam may cause malfunctions. Please contact PISCO sales office in your region for more details.
If the system is sealed or nearly sealed, ensure that the temperature inside the system stays below 40°C (104°F). Although it depends on the heating level of adjacent apparatus, ensure that there is at least a 5 cm interspace around the pump.
Also, when setting up Rotary Vacuum Pump and having the clearance for ventilation, please take into account the precautions (1) to (3) as listed below.
(1) Securing ventilation for pump cooling air
The concentrically arranged multiple long holes on the opposite side of the motor are the “cooling air inlet openings” for the forced cooling of the pump.
The multiple slits between the motor and pump (where the rotation of the fan can be seen) are the “cooling air exhaust openings” for the forced cooling of the pump. (*See the figure below.)
Please ensure that the flow path does not hinder ventilation to the aforementioned “cooling air inlet openings” and “cooling air exhaust slits” for the forced cooling.
(2) Securing ventilation for motor cooling air
A motor with rated power 60 W or 90 W is equipped with a cooling fan at its end. "Air inlet holes for motor cooling" is located on the end facet of the motor. Please ensure that the flow path does not hinder ventilation.
(3) Natural heat dissipation from the pump surface
Besides the ventilation mentioned above, the surfaces of the pump and motor dissipate heat. To prevent the heated air by dissipation from staying around the pump, please take measures such as securing ventilation space and blowing air with a separately installed fan.
Except for custom-made, Rotary Vacuum Pump complies with the following standards.
CE marking

*) Please check the link below for standards, etc.
We don’t have cleanroom-specific motors available.
Therefore, you need to take measures such as covering the motor, etc. Please contact PISCO sales office in your region for consultation.
The ambient temperature around Rotary Vacuum Pump should be 5 to 40℃.
A cover arranged by a customer sometimes may cause the retention of ambient air, which in return could cause the pump and motor to generate heat. Be cautious not to let the pump's ambient temperature go beyond 40°C, and avoid installing it too close to the heat source. Otherwise, the load inside the pump may increase abnormally.
Suspend operation of Rotary Vacuum Pump if you feel the ambient temperature being high. Please be careful not to burn your hand when touching the pump. Resume operation after the main unit of Rotary Vacuum Pump cools down, and the temperature inside the cover drops.
Please refer to the following specifications for Exhaust Air Cleaner.

VFU can be easily installed in the middle of piping and has low piping resistance, while also being stable.
Be sure to install a filter on the suction side because the suction of foreign substances, such as dust, can cause malfunction.
If Rotary Vacuum Pump stops due to sucked foreign substances, do not attempt to forcibly remove foreign substances or disassemble the product on your own. Please contact PISCO sales office in your region so that we can replace it or perform maintenance.
Fluorine-based grease with the least volatile level base oil [Base oil: perfluoropolyether (PFPE) oil, thickener: PTFE)] is used on the sliding part of the Rotary Vacuum Pump.
All the motors used in Rotary Vacuum Pump are induction motors with built-in thermal protectors.
AC motors can be broadly classified into two types: synchronous motor and induction motor, with the latter generally being the most widely used. The induction motor has a squirrel cage-like structure and is described sometimes as "squirrel cage induction motor".
Induction motors can be divided into single-phase and 3-phase motors based on the type of AC supply. Visually, the motors differ in the numbers of wires they have, with a single-phase motor having two and a 3-phase motor having three.
Single-phase motor
Since the single-phase motor does not start rotating on its own, the current flow is adjusted by adding a capacitor in the circuit so that its alternating current can rotate the motor. Because there is less wiring and low voltage, the safe single-phase motor is chosen for common household use.
3-phase motor
When switched on, the 3-phase motor generates a rotating magnetic field to start rotating on its own.
Its smooth rotation and high output power are favored for industrial use in factories, etc.
The 3-phase motor combines three single-phase alternating currents to rotate the motor with three-phase alternating currents that are displaced by 120°per rotor rotation.
Specifications and environmental conditions
Tolerance range of power supply voltage: ±10% (It is the acceptable range of power supply voltage fluctuation, not the voltage level that can be used at all times.)

Please refer to PISCO catalogs for basic specifications.
For "Cautions for installation", "Thermal protector", etc., please refer to the related topics.
A thermal protector protects a motor from overheating or damage by heat due to the motor overload.
The thermal protector built into the motor for PISCO Rotary Vacuum Pump automatically restores itself. If the thermal protector is activated due to motor heat generation and stops the motor, it will restart automatically after the motor cools down. To avoid this automatic restart, it is recommended to make a self-retention circuit with SW (switch) and Ry (relay). For safety, make connections as shown in the circuit diagram below.
It is not advisable to use Rotary Vacuum Pump without a thermal protector. Without a thermal protector, an overload on the motor could result in motor damage by heat or, in the worst-case scenario, catch fire.
RPV064 series has a self-restoring thermal protector in the winding part of the motor. After activation, the thermal protector will automatically resume operation once the motor temperature drops. To avoid danger caused by unexpected restarts, please take safety measures such as installing a self-retention circuit with a relay and switch when using Rotary Vacuum Pump.
Rated voltage: 250 VAC 3A
Activation temperature
For single-phase and 3-phase including RPV064-120, please refer to the Instruction Manual of the product on PISCO website.
Although some parts are made of flame-retardant grade materials, Rotary Vacuum Pump as a product is not UL certified.
Motor (purchased)
UL recognized
Rotor (Resin component)
flame-retardant grade UL94-V-0
Cooling fan (Resin component)
flame-retardant grade UL94 V-0
Sealing cup for magnet coupling (Resin component)
flame-retardant grade UL94-V-1
There are other non-metal components not mentioned above, such as rubber-made O-ring and check packing, all of which are made of fluorine rubber. However, they are not within the scope of flame-retardant grades, etc.
*) The UL marking on the motor nameplate is intended for the motor alone. It does not indicate that Rotary Vacuum Pump is UL certified.
When setting up multiple units of Rotary Vacuum Pump in a piece of equipment, the basis is one Exhaust Air Cleaner for each Rotary Vacuum Pump.
Using only one Exhaust Air Cleaner for two units of Rotary Vacuum Pump will cause blockage of the exhaust port and increased back pressure. Then, the increased load on the units may result in heat generation.
Additionally, the piping between the exhaust port and Exhaust Air Cleaner should be large and short to the extent possible. If adopting tube exhaust, make sure that the piping diameter is sufficient enough to prevent back pressure from increasing on the exhaust port side of the pump.
It is controllable with the following circuit.
Red enclosed area…24 VDC area
Blue enclosed area…Self-retention circuit
A thermal protector is polarity-insensitive. (Think of it as a position switch with contacts.)
In the diagram above, positive polarity is the input for the thermal protector, but negative polarity can also be applied. (Please note that relays are polarized.)
Pressing SWA will activate the motor.
If the thermal protector is triggered by an incident such as a temperature rise, then the relay senses it and activates to stop the motor.
Pressing SWB will release the self-retention, and repressing SWA will reactivate the motor.
*) The thermal protector on this motor is self-restoring. When there is no self-retention circuit, the motor will resume operation once the temperature drops and the thermal protector is released.
There are two ways to measure pressure: absolute pressure and gauge pressure.
Absolute pressure
Absolute pressure is measured in respect to the absolute zero pressure, which is a perfect vacuum.
It is commonly used to measure the pneumatic flow rate, etc.
Absolute pressure is denoted with “abs” at the end of the pressure unit. (Ex. 10 kPa abs)
Gauge pressure
Gauge pressure is zero referenced against ambient atmospheric pressure at a location and time of measurement.
It represents how much pressure is applied to an area of 1 cm2 based on atmospheric pressure. It is commonly used for indication of the manometer. The pressure above the ambient atmospheric pressure is called “positive pressure”, and the pressure below the ambient atmospheric pressure is called “negative pressure”.
The torr is a unit of pressure/vacuum measurement that was widely used before the pascal (Pa) and hectopascal (hPa) in the International System of Units (SI) were introduced. (Absolute vacuum is 0 torr, and standard atmosphere is 760 torr)
The torr, also known as the “millimeter of mercury (mmHg)” is a non-SI unit of pressure that is still being used in many fields.
1 Torr = 133.32 Pa
1 atmospheric pressure = 1013 hPa = 1.01325 x 105 Pa = 760 Torr
*) 1 pascal is 1/100th of hectopascal used in weather forecasting.
