Circulation Pump DPS Series

Working Conditions

Pumped medium temperature scope: 0℃- +90℃

Maximum application environment temperature: +40℃

Medium requirement: clean without sundries, mineral oil, stickiness, and corrosiveness

Chemical property: the property is closed to neutral without explosiveness and it is like liquid of water (the content of ethylene glycol is up to 30%)

It is necessary to consult the manufacturer first if other liquids are extracted

Maximum operating pressure: 5 bar

Minimum inlet pressure: When the temperature is +50℃ 0.05bar
When the temperature is +70℃ 0.3bar When the temperature is +90℃ 1.0bar
The above-mentioned values are only applicable for elevation of 300m; as for the higher elevation, 0.01 bar should be added for every 100m increased. To prevent noise generated by cavitation erosion, the minimuminlet pressure should be maintained.

The pump should be operated between±10% of the rating voltage; if the voltage is too low, the pump will be overloaded, which will lead to temperatureincrease of engine and decrease of pump head & pressure curve.

Product Use

The pump is applicable for cold/hot water circulation and pressurization; particularly, the shower set might lead to fire because of low or unstable water pressure and installation & application of this pump can easily totally solve the problem

It is also applicable for pressurization water supple of the household low water pressure, water supply of solar water heater, hot-water circulation of boiler, and circulation pressurization of air conditioner & refrigerating system.
