The client, Mr. Chengtai’s team from Zimbabwe, is working on a 35,000 square meter irrigation project for a local farm. Come to our company to investigate the OS, ES and other models of the middle open pump. Warmly received by the company boss.

Communicate with company technical personnel for detailed requirements and technical parameters.

Project product introduction:

Overview:

With years of experience in the manufacturing double-suction pumps, we analysed the common pain points for customers, we designed a brand-new pump solution - Series ES Environmental Protection Horizontal Double Suction Split Casing Centrifugal Pump - in collaboration with domestic professionals and expert abroad. (Horizontal pump patent number: ZL 2018 2 2092944.2. Vertical pump patent number: ZL 2019 2 0293130.7). This new solution stands out in its environmental friendliness and maintenance-free feature.

Main features:

Eco-friendly

The traditional grease-lubricated bearings (including both rolling contact bearings and sliding contact bearings) are replaced with self-lubricating sliding contact bearings, eliminating the pollution hazard to both the transmission medium and the site environment. 

Energy-saving

1.Lubricant is no longer needed

2.Less material used

Traditional bearing body removed

Shorter pump shaft – reduce one mechanical seal

3.Increased efficiency

Hydraulic model improved and optimised

Changes in structure and lubrication methods improve efficiency 

Maintenance-free and low operation cost 

1.Maintenance-free bearing eliminates manual inspection

2.The non-driving end seal adopts static seal technique，eliminating one mechanical seal

Longer bearing life

The service life of traditional ball bearings is affected by the operating conditions. The general design life is about 2-5 years. With this product, the bearing service life can reach 5-10 years.

Safer, smoother, and more reliable operation

Carefully designed to reduce vibration and noise.

The non-driving end adopts static sealing, which reduces one point of failure.

The bearing cage of the traditional double-suction pump is removed, the length of the pump shaft is shortened, improving the operational stability of the pump.

Diaphragm coupling for the full range of pumps.

Wider application:

A variety of material combinations can be chosen according to different purposes, allowing for a wider range of application.

Simpler structure, easier repair

The original advantages remaining unchanged – the casing is split into two parts. Inspection work

only needs the upper casing to be dismounted, instead of the main distribution piping.
