Product Description

Shanghai Crowns Pump Manufacturing Co., Ltd. offers top-quality water pumps. Horizontal Multistage Centrifugal Pump CHL constant pressure frequency conversion water supply system is composed of newest great performance PID frequency conversion controlling cabinet and more than 2 pumps. It is the top technical water boosting equipment, which can automatically adjust to satisfy the requirement of constant pressure, variable water demand. The pressure of water supply net can be kept constant. The whole water supply system can be at best effective, energy saving, perfect status. There are two ways of water supply, they are frequency convention water supply and pressure water supply. Frequency water supply is automatically adjust the rotation speed of one pump or run/stop one or more pumps, which is the best water supply way to keep the water supply net to be stable. It is easy to use.

● Convey liquid: cold, warm, clean, non-flammable, non-explosive liquid, not consisted of solid grain or fiber.
● Medium temperature: Normal temperature type -15°C~+70°C; Hot water type + 70°C~+ 120°C;
● Ambient environment: No drop, vapor, no floating dust or metal grain. No sunshine, hot temperature, heavy dust. No corrosive, non-flammable gas or liquid.
● The equipment should be placed in no vibration place and in the place where it is easy to check.
