Design Features

The G/GH series gravel pumps are all centrifugal pumps with horizontal and single pump casing structure, of which the GH type is a high-head gravel pumps.

The G/GH series gravel pumps adopt a single casing connected by means of clamp bands and wide wet-passage. The wet-end parts are made of Ni_hard and high chromium abrasion-resistance alloys.

The discharge direction of pump can be oriented in any direction of 360°. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance.

The main types of pump shaft seals are packing seals, expeller seals and mechanical seals.
