WH-PMPP-62 constant pressure pump 6 plus 2 minus

1. introduction

WH-PP-62 constant pressure pump is an 8-channel pressure control system developed by Wenhao Co., Ltd. . The system consists of 6-channel positive pressure control switches and 2-channel negative pressure control switches. The system has the advantages of high precision, stable performance, strong anti-interference ability, and optional multi-pressure range. It is widely used in the field of long-term controllable gas and liquid transportation. The utility model is suitable for microfluidic chip injection, chemical reaction injection and long-time drug injection, etc. . The instrument is equipped with a large touch screen, making the operation more accessible and more convenient.

The WH-PMPP-62 constant pressure pump is mainly used to control the gas pressure through the pressure regulating valve. It can control the gas pressure of 8 channels independently.

2. Feature diagrams

Note: If the air pressure needs to be greater than 0.4 mpa, make sure the main input air pressure is large enough (less than 0.7 mpa) , adjust the pressure filter to increase the input air pressure; in general, the pressure filter set to 0.4 mpa;
