Super Engineering Plastics (WPM1 model)


Super Engineering Plastics

In response to customer requests, we have added the WP1100 model that maintains the same basic design of the WP1000 series but is compatible with tubes of inner diameter 6.4mm (1/4"). The WP1100 supports flow rates of up to 700 mL per minute and the use of various types of tube materials.
(The dimensions and shape are different from those of the WP1000.)

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.

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.
