Product Description
-Eco-friendly
The traditional grease-lubricated bearings (including both rolling contactbearings and sliding contact bearings) are replaced with self-lubricating sliding contact bearings, eliminating the pollution hazard to both thetransmission medium and the site environment.
-Energy-saving
A. Lubricant is no longer needed.
B. Less material used.
C. Increased efficiency.
-
Maintenance-free and low operation cost
A. Maintenance-free bearing eliminates manual inspection.
B. 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
A. Carefully designed to reduce vibration and noise.
B. The non-driving end adopts static sealing, which reduces onepoint of failure.
C. The bearing cage of the traditional double-suction pump isremoved, the length of the pump shaft is shortened, improving theoperational stability of the pump.
D. Diaphragm coupling for the full range of pumps.

Pump casing & Casing cover
The pressure chamber of ES type double suction pump has a trapezoidal cross-section. To avoid shape distortion due to casting errors, the flange of the casing cover is designed to be slightly larger than the flange of the casing.For a split casing pump with a lower head, a single-shell structure is used. To reduce the pressure pulsation during the operation, the diaphragm tongue of the pump pressure chamber is designed with an inclined shape.For a split casing pump with a higher head, the radial force generated when the pump is running is large. Hence a double volute chamber structure is adopted.

Changes in structure and lubrication methods improve efficiency
The bearing of the ES type double suction pump is a self-lubricating bearing located inside the pump body to support the rotor components.lts biggest advantage is maintenance-free (that is, no daily maintenance is required). lt has the advantages of small installation space, stable operation, high efficiency, low operation and maintenance.
