high quality DAYUAN vacuum diaphragm pump

Specifications

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

  

  GPD series circulation pumps

 

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.
