Super Engineering Plastics (WPM1 model)
Super Engineering Plastics
Super engineering plastic, having excellent corrosion resistance, is used for the main tube parts and enables the pumps to be used with strong acids, strong alkalis, and chemical solutions that erode general-purpose plastic.  The heat resistance is also excellent, use in various environments can be supported.

 

Fluid temperature 5°C to 50°C
Material(Pump parts) PSU (Cassette/Rotor/Base), POM (Roller, etc)
Autoclave Not Available

 

Compatible with autoclave sterilization (WPM2 model)
Compatible with autoclave sterilization
(WPM2 model)
All parts of the WPM2 pump cassette are made of super engineering plastic that has excellent heat resistance. Autoclave sterilization can now be performed on industrial-use compact-size peristaltic pumps.
Pump operation supports liquid solution temperatures of up to 80°C.

 

Fluid temperature 5°C to 80°C
Material(Pump parts) PSU (All parts)
Autoclave Autoclave condition: 0.1 MPa, 121deg, 20 min Only the Pump parts.

Note: Autoclave sterilization is assumed to be performed under the conditions of 0.1 MPa (121°C) for 20 minutes.
Number of autoclave is supposed less than 30 times.(except pump tube)
If the actual conditions will exceed these values, be sure to perform a confirmatory evaluation. Even when using tubing that can be autoclaved, performing the autoclave sterilization process while the tubing is fitted to the pump may cause the flow rate to change. If this is a concern, remove the tubing and sterilize separately.

 

 

Motor variation

The lineup also includes various types of motors for mounting, such as 12 and 24VDC low-speed and high-speed motors, stepper motors, brushless motors, etc.

*UL: Except CA type

Note:

*1

The tubing on the discharge side may rupture if blocked, resulting in a potentially dangerous situation.
Be sure to design the discharge side such that the pressure is less than the discharge pressure.

*2

Autoclave sterilization is assumed to be performed under the conditions of 0.1MPa (121°C) for 20 minutes.
Number of autoclave is supposed less than 30 times. (except pump tube) If the actual conditions will exceed these values, be sure to perform a confirmatory evaluation.  Even when using tubing that can be autoclaved, performing the autoclave sterilization process while the tubing is fitted to the pump may cause the flow rate to change.  If this is a concern, remove the tubing and sterilize separately.
