Constant Pressure Pump VSD Inverter We make VSD inverters especially for water pump, they have better performance, better stability and simpler operation. In fact, when the VSD inverter is installed and used, or it is disassembled, you will know the quality difference PRODUCT DETAILS Products Feature •This Constant Pressure Pump VSD inverter is used especially for clean water pump, with the industry leading technique SPWM & pressure transmission technique, it detects actual pipeline pressure change and Controls the opération speed of the pump.. •Simple opération: easy to use, ail functions can be terminated by pressing a button, without the need to hire programming specialists. * •Energy efficiency. Compared to the traditional water supply method, the constante Pressure water supply system with frequency converter saves up to 30%-60% of* Energy.* •Long-term reliability of the co-operating pumps: the average torque and shaft wear are reduced due to decreasing the average rotational speed, which increases the pump operational lifetime. Due to the built-in soft start and stop function, the device allows to eliminate the water hammer (the water hammer is a sudden pressure increase that occurs at rapid stopping or starting of liquid flow.)* •LED display makes it convenient and fast to check and set actual pressure values.*
