Finally a Dry Running Magnetically Coupled Pump
Available in Polypropylene or ETFE the Chem Free GV From Chem Resist offers a long term dry running capability and corrosion resistance.
A typical magnetically coupled plastic pump can run dry for a short periodsay 1-2 minutes without too much risk of damage.The reason for this is that the pumped liquid also acts as a coolant transferring heat away from the rotating parts such as the bearing and shaft.
In a normal Magnetically Coupled Thermoplastic Pump When this inlet liquor is unavailable, the rotating parts of the pump will heat up either melt the surrounding plastic body of the pump or damage can also be caused by operators putting cold liquor back into the pump while it is in this heated state and cause thermal shock that can shatter shafts and damage bushings.
The Self Priming Chem Free GV From Chem Resist overcomes this expensive problem by a volume of liquor held in the pump chamber even after the inlet pipe-work has been emptied. This liquor constantly provides cooling to the rotating parts and allows the pump to run without liquor on the inlet for prolonged periods.
The exact period of time can be calculated by the time it takes for the liquor to rise in temperature so as to evaporate. Typical temperaturerise would be about 1 degree per minute for a water like liquid.
As well as this protection against the effects of dry running the Self Priming Chem Free GV also is the fastest Self Priming Pump of its kind, able to prime 5 metres in under 2 minutes.
There's too much to describe here, so if you would like to learn more or to request an on site demonstration of the Chem Free GV pump, without cost or obligation contact Chem Resist by phone or e-mail.
