hot water booster pump
1.cast iron pump body,
2.low noise screened electric pump

Product Description

Application:

Single-phase canned motor circulation pumps designed and produced by our specialists have these features: low noise, no leakage, ecological safety in operation, artistic appearance, easy installation and reliable operation. Pumps can be used in single tube or double tube heating system, also can be applied to city apartments, suburb villa, cooling, air-conditioning, boilers and solar systems etc.

Working conditions:

1. Pump supply: voltage 230V, frequency 50Hz, single-phase AC power. The models listed in the table can also be manufactured according to user’s requirement as 230V/60Hz or 115V/60Hz.

2. Maximum system pressure 1.0 MPa.

3. Temperature of environment: 0°C to 40°C, temperature of pumped liquid: 2°C to 110°C (except for models with automatic switch (GPD-A). In order to avoid condensed water in stator make sure that the temperature of environment is lower than liquid temperature.

4. Maintain minimum pressure at the pump inlet to avoid cavitation noise and damage on pump bearings.

5. Pumped liquid: thin, clean, non-corrosive and non-explosive does not contain any solid particles, fibers or mineral oil. Pump must not be used for delivering flammable liquids, such as diesel and gasoline. Delivering liquid of high viscosity will reduce performance of the pump, so while choosing a pump, the viscosity of the pumped liquid must be taken into account.

Q:What are the ways of hydraulic pumps?
There are several ways:Direct flow mode, such as external gear pump;Port plate, such as vane pump, axial piston pump, etc.;
Q:Why can't the inlet of centrifugal pump be negative pressure?
Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.
Q:What does electromechanical vector pump mean?
It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.
Q:What is a vacuum pump for?
Aquaculture, screen printing machine, photographic plate machine, injection molding machine, automatic feeding machine, paper transport...
Q:What's the word "pump"? Is that what advocates mean?RT
What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Submersible pump is best in the water, if dry pumping will cause burns.
Q:Why is the flow of the pump too small will occur cavitation phenomenon?
Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.
Q:What are the internal losses in centrifugal pumps? How did they come about?
Hydraulic loss: the loss of water by friction, eddy, impact, etc in a flow;
Q:Constant pressure pump working principle
The pressure loss is borne by the valve. Constant pressure pumps generally do not export direct load, unless you need this load response is very fast, then the maximum displacement of the pump work, so as to ensure the rapid response of the load.
Q:Rules for operation of centrifugal pumps
Operating rules:1, before starting to check whether the water pump foot loose, coupling shield, and motor fan blade cover is intact, in order to ensure the safety of equipment and personal safety.2. Check whether the inlet valve is open and open as fully as possible. Is the outlet valve closed, open the bleeder valve, exhaust until there is no air, and close the bleeder valve. At the end of the valve to the pipeline in the pump cavity filled with water.
