Features

120W Grundfos automatic whole sale circulation pump, booster pump, cold and hot water pump
1. Long life: pump and motor form a whole unit, stainless steel sets of rotor and stator completely shield the two isolated cavity to heat the liquid into the pump, greatly slow down the insulation aging.

2. No leak: without mechanical seal, only two gaskets for sealing enclosure, so it is a more effective way to eliminate fluid leaks.

3. Anti-high temperature: impeller and motor are made from high temperature resistant material, suitable for conveying water which temperature is from 2 degrees celsius to 110 degrees celsius.

4. Anti-wear: Ceramic bearings are good at hard wear-resistant, compared to the previous graphite shaft is more robust, more wear-resistant, longer service life.

5. Ultra-quiet: sleeve through the pumping of liquid lubrication, lower noise, listen carefully otherwise can not hear any noise.

6. High efficiency: centrifugal design for impeller, big flow and high efficiency.

Advantages:
1. Built-in automatic switch , easy to use.

2. Low noise, completely silent. Sound wave is below EC EEC machinery and equipment standards.

3. Environmental protection, pump body is corrosion prevention (electric spray), and there is a vent behind the motor.

Performance:
i) Fluid temperature range: 2^oC - +110^oC
ii) Max. working pressure: 10 bars
iii) Ambient temperature: permissible up to 40^oC

Motor:
i) Degree of protection: lp44
ii) Insulation class: F

Pump equipment:
i) Pump body: cast iron
ii) Impeller: PPO, stainless steel on request
iii) Shaft: porcelain
iv) Bearings: graphite or ceramic

a) Pump shaft in the horizontal plane, terminal box
b) Screwed end single head pump
c) Manual 3-speed control or Automatic type
d) Non-overloading single phase motor

Notice:
1, Let pump work for a few minutes after installed. (check the boot is normal or not), but the idle time can not be too long (in 5 seconds), to prevent decreasing the life of ceramic bearing.

2, Before installing pumps, you should ensure that there is no slag in pipeline , if there are impurities, welding slag, dirt, etc. will damage the pump life.

3, Note exhaust of pump at the first time of running, it can not booster if there is air in pump. You can exhaust one time when hot water circulate for a week.
