Pumps are made to DIN 24256 in back-out design. Non-back pull-out pumps in smaller sizes are also available.
All wetted parts (volute casing, back cover, impeller) are pressure-cast to shape in solid sturdy construction in UHMWPE - the toughest polymer exhibiting superior properties such as :
Widest chemical resistance- nearly all chemicals (acids, alkali, salts, reagents etc.)
Withstand higher temperature - 90 to 95oC without deforming. Toughest at sub-zero!
Highest abrasion resistance of all polymer materials - matching exotic alloys!
Exceptional impact strength - pump parts don't crack!
Very low friction-coefficient results in better pump efficiency.
Impeller is semi-open type with metal bush moulded insitu, which does not dissociate from polymer due to the thrust and torsional loads of its motion.
Pressure casting of pump parts in special moulds ensures interchangeability and standardization, results in regular smooth contours of volute and impeller vanes. There are no threaded or welded joints in the wetted parts.
Shaft sealing is provided through packed gland or suitable mechanical seals of reputed make.
Shaft sleeve is made from compatible materials such as Hastelloy, Alloy-20, SS-316, Ceramic etc.
Pump capacities cover flow upto 400M3/H, heads upto 80 M. Pumps of higher capacities can also be developed against specific requirement.
