Hms Pumps

Construction :
* The HMS pumps have horizontal foot mounted design, single or multistage, with vertically split suction, intermediate and discharge casings.
* The casings are clamped together by external tie-bolts and sealed with Gasket. '0' rings are required for the design, pumping temperature of the liquid and the construction of the pump.

Sealing Arrangements :
* Conventional soft graphite packed stuffing boxes are incorporated on either side of the pump. The shaft is fitted with the renewable shaft sleeve in the region of the stuffing boxes, which protects the shaft from wear due to packing.
* This standard construction is recommended for operating temperature up to 90 degree C.
* For higher temperature from 90 to 140 degree C, special water jacketed stuffing box are fitted, which maintain the temperature in the stuffing box region within acceptable limits.
* For special applications, special design of stuffing boxes or mechanical seals can be fitted as required.

Impellers :
* HMS Impellers are made of close grained cast iron, enclosed type, machined all over.
* The outer surfaces are finished by hand.
* The impeller with rotating assembly is dynamically balanced to eliminate vibrations.
* Pumps with phosphor bronze or stainless steel impellers can be supplied on request. Open or closed impellers are available.
