H Series Rotary Gear Pump

H Series Rotary Gear Pump is a Positive displacement, self-priming, foot mounting type H series gear pump. Model "K.I. H Series Rotary gear pump" has a straightforward two-piece cast iron construction with a single helical modified profile carton steel gear shrink fitted on an alloy steel shaft that has been hardened and ground finished. The gear is firmly supported by 4 nos. of self-lubricating bronze bush bearings, which ensure smooth operation. By shifting the position of the inlet-outlet ports, these pumps can be operated either way. Simply shifting the relief valve's position will reverse the relief valve's operations.

What is the H Series gear pump designed for?

The "K.I" Rotary Gear Pumps were created with high- and low-viscous liquids in mind. The Pump's body, covers, big cavity gears, and MS shaft are made of close-grained cast iron. The pump consists of two gears with huge cavities and carefully cut tooth profiles that can easily pump a variety of highly viscous liquids. These gear pumps have no trouble handling liquids such as wax, soap, tar, bitumen, and asphalt.

Characteristics of H Series Rotary Gear Pump

H Series Gear Pumps are the most adaptable rotary positive displacement pumps, outperforming other types of pumps. As a result, they are used for the broadest range of applications, including loading and unloading, transfer, fuel pressurizing, hydraulic, lubrication in IC engines, polymer metering applications, and more. By tightening the operating clearances and increasing the craftsmanship, gear pumps may create high pressure in the same design, but screw pumps require longer threads, making them bulky and challenging to construct.

H Series Rotary Gear Pump is efficient since each tooth gap adds to the capacity, whereas just one pitch length does so for screw pumps. However, some liquid always passes to suction due to running clearance between the casing & impeller creating a slip, which relies on the differential pressure, the viscosity of the liquid, and workmanship. The pump's capacity varies directly with speed but remains constant against pressure. Gear pumps can handle liquids of any viscosity; as viscosity increases, frictional power increases, while slipping decreases. Despite the pump's ability to self-prime, some net positive suction head is always necessary to prevent cavitation; this again relies on the liquid's viscosity and the pumping speed.
