Horizontal multistage stainless steel centrifugal pump
CHME (VFD)
Constant-pressure variable-frequency horizontal pumps, CHME
A complete constant-pressure unit: the pump is supplied with its frequency controller, pressure sensor, five-way check valve, pressure gauge and pressure tank. The controller varies the motor speed between 30 and 60 Hz to hold the set pressure. All flow parts are stainless steel; working pressure up to 10 bar.
- Controller, pressure sensor and tank included
- Speed range 30–60 Hz (variable frequency)
- All flow parts stainless steel, up to 10 bar
- Home water supply, filtration and cooling water
