Frequency constant pressure water
Frequency constant pressure water

Frequency constant pressure water supply equipment is a new type of energy-saving water supply equipment. The variable frequency constant pressure water supply equipment takes the water pressure at the outlet of the pump (or the user's water flow) as the setting parameter, and automatically controls the output frequency of the inverter through the microcomputer to adjust the speed of the pump generator, so as to realize the closed-loop adjustment of the water pressure of the user's pipe network, so that the water supply system automatically keeps steady at the set pressure value


Constant pressure water supply advanced technology, constant water pressure, easy operation, reliable operation, energy saving, high degree of automation, in the pump station water supply can complete the following functions:

1.Maintain constant water pressure
2.The control system can be operated manually/automatically
3. Multiple pumps automatically switch operation;
4.System sleep and wake up: when the outside world stops using water, the system is in a sleep state until it automatically wakes up when there is water demand;
5. Adjust PID parameters online
6.Pump group and line protection detection alarm, signal display, etc


System application scope

1, water plant, pressure pump room
2. Residents' living areas, hotels and other buildings
3, enterprise production water
4, boiler circulating water system
5. Farmland irrigation system

Ruichen Pump experienced personnel carefully evaluates the customer’s needs, paying attention to all the technical data. In particular, the following data are the most important in order to choose the right pump: capacity/flow and head/pressure required, kind of liquid, concentration, temperature, viscosity, possible presence of solids in suspension and if known also NPSHa.

Which is the best material for a pump?

When you talk about pumps for acids the choice of the material depends on different aspects. Our high-skilled personnel can help you in this evaluation by collecting some data about the kind of corrosive liquid you have to pump, the concentration and temperature. Our chemical compatibility charts, created according to our decennial experience, are very useful in these cases, but it’s necessary to perform a deep analysis of the final application and of the required performances in order to select the correct chemical pump model. Our technicians are always available to select the correct pump and the best material for the customer’s application.
