G/GH Sand Gravel Pump Suppliers & Manufacturers

Single Casing Structure: Construction of this pump is of single casing connected by means of clamp bands. Simple design for easy maintenance and installation.

Wide Wet-passage: It can transport large particles with higher abrasive slurries, which is more adaptable

Flexible Discharge: The discharge direction of pump can be oriented in any direction of 360°. This type of pump possesses the advantage of easy installation.

ADVANTAGE OF G/GH Sand Gravel Pump

High Abrasion Resistance

The wet-parts are made of Ni_hard and high chromium abrasion-resistance alloys. High hardness and long service life.

Good Performance Of NPSH

It can also operate stably under the condition of low NPSHr and adapt to complex working conditions.

High Head Design

GH type is a high head gravel pump, which can meet higher transport needs.

STRUCTURE OF G/GH Sand Gravel Pump

Bearing Assembly

The bearing assembly is the key component that supports the rotation of the impeller and is usually made of high quality roller or plain bearings.Its high precision and low friction can ensure the smooth operation of the impeller.The bearing assembly of G/GH gravel pump adopts cylindrical structure, which is convenient for adjusting the clearance between the impeller and the cover plate liner, and can be dismantled as a whole during maintenance, which is simple and convenient.

Base

Base is an important part to support and fix the bearing assembly and pump shaft, which is usually made of high-strength materials to ensure the overall stability and operational reliability of the pump.

Stuffing Box

Stuffing box is used to install packing seal, which is the key part to prevent the liquid in the pump from leaking and the outside air from entering.The stuffing box of G/GH gravel pump is well-designed, which can effectively reduce the leakage, and can choose packing seal, expeller seal, mechanical seal and other sealing forms according to the needs.

Frame Plate

The frame plate is one of the main parts of gravel pump, adopting single casing structure, with wide and smooth flow wet-passage, capable of conveying large particles of strong abrasive materials.The material is usually high chromium alloy or wear-resistant alloy steel, the hardness is not less than 58HRC, with good anti-abrasive properties.

Clamp

The clamp is used to connect the frame plate and the frame plate liner insert, and adopts a special clamping structure, which can make the bowl and the door tightly connected, and at the same time allows the pump discharge direction to rotate within 360° at will, and it is very convenient to install and dismantle.

Door

The door is mounted in front of the impeller to protect the inside of the casing from wear.Its material is the same as the casing, usually high chromium alloy or wear-resistant alloy steel, with good wear resistance.

Impeller

The impeller is the important part of the gravel pump and is responsible for drawing liquid in and discharging it.Its vanes are uniquely designed to handle oversized materials while minimizing intrusion of highly concentrated solids into the seal area.The impeller material is high chrome alloy with high hardness and wear resistance.

Frame Plate Liner Insert

The frame plate liner insert is mounted behind the impeller and together with the door protects the inside of the casing from wear.The material is the same as the door, usually high chrome alloy or wear-resistant alloy steel.

Adaptor Plate

The adaptor plate is a key component used to connect the casing and the frame plate liner insert. It is linked to the casing and the frame plate liner insert by a clamp to ensure sealing and stability, and at the same time, it is easy to install and dismantle.
