WPM Products configuration
38 mm diameter ultra-compact full-spec model
WPM1 Feature
The rollers are made of POM, but other parts are made of super engineering plastic (PSU) which offers excellent corrosion resistance. This allows the pump to handle acids, strong alkalis, and any other general chemical solutions.

WPM2 Feature
All parts of the WPM2 cassette are made of a super engineering plastic (PSU), which provides superior chemical resistance and enables high-temperature liquid transfer compared to the WPM1 pump series. The entire cassette is also autoclavable.

| Autoclave | Condition: 0.1MPa, 121°C, 20min (only pump cassette) |
Note:
Autoclave sterilization is assumed to be performed up to 30 times. Please note that not all tube types are suitable for autoclaving. For specific tubing compatibility, please contact our sales representative. Autoclaving the cassette with the tubing installed may result in a decrease in flow rate.
Please evaluate under actual operating conditions, and if necessary, remove the tubing before autoclaving.
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.

Please refer to chemical resistant properties for tube selection. It is the user’s responsibility to ensure the suitability and safety of tube for all intended uses, including establishing the compatibility of any fluid with the tubing through which it is transmitted. Laboratory, field or clinical tests must be conducted in accordance with applicable requirements in order to determine the safety and effectiveness for use of tubing in any particular application. If intended for medical use, it is the user’s responsibility to ensure that the tubing to be used complies with all applicable medical regulatory requirements.

Note:
*1
If the discharge side becomes blocked, the tubing may rupture, potentially resulting in a hazardous situation.
To prevent this, ensure that the discharge side is designed so that the pressure remains below the pump's discharge pressure.
*2
Autoclave sterilization is assumed to be performed up to 30 times. Please note that not all tube types are suitable for autoclaving. For specific tubing compatibility, please contact our sales representative.
Autoclaving the cassette with the tubing installed may result in a decrease in flow rate.
Please evaluate under actual operating conditions, and if necessary, remove the tubing before autoclaving.
