Automotive Water Pumps

Product Description

Majority of modern engines are liquid cooled, as opposed to the older air-cooled engines. To pump this coolant through the engine is the work of the engine water pump, or the coolant pump. Usually these are centrifugal pumps that circulate water (or coolant) through the various cooling channels cast into the head and the block. The coolant collects the heat and dissipates it through the radiator.

Water pumps are more susceptible to leakage issues than lubricating oil pumps since the liquid being pumped is much less viscous and can easily make its way through minute cracks or fitment gaps of the rotor seals. Quality of the seal is the single most important factor that determines the reliability of these pumps. A malfunction in the water pump leads to rapid increase in the operating temperature of the engine leading to expensive downtime of the machinery. If ignored, it will ultimately lead to engine seizure. AutoGRACE  brand water pumps are manufactured by the leading manufacturers of automotive water pumps in India, using only the best quality seals.

These pumps can be categorized into:

OPEN PUMPS

The pump is bolted directly onto the block and sealed using a flat gasket or sealing ring.

CLOSED PUMPS

These are self-contained assemblies and are mounted independent of the engine block.

DRIVE TYPE

Both closed and open type water pumps may be driven directly by the engine using gears, or by using plain or ribbed V-belts and timing belts of the engine.

IMPELLERS

The latest fluid dynamics models are used to design impellers that maximize pumping efficiency while considering manufacturing limitations. Impellers may be made of plastics, cast iron, steel, aluminum or brass.

Garima Global has also developed improved versions of OEM pumps by replacing plastic  fiber impellers with cast iron ones to make them more durable.
