Technical Features

Bearing Details

Between-the-bearings Design: Split-case pumps mount the impeller on a shaft supported by bearings on both sides, ensuring stability and balanced loads.

Double-suction Impeller: Dramatically reduces loads on the bearings compared to single-suction types. High-precision casting available in cast iron, stainless steel, or bronze.

Seal Details

Sealing Solutions: Traditional Packing Seals are available for wide-ranging utility, while Mechanical Seals are preferred for leak-free operations and enhanced durability in demanding applications.

Coupling Details

Flexible Couplings: We utilize wear-resistant disc or pin couplings to accommodate vibrations and thermal expansion, protecting shafts and bearings from premature wear.

Frequently Asked Questions

What is the main advantage of the split-casing design?
The split-casing design allows for easy maintenance. The pump cover can be removed to access internal parts without disturbing the inlet and outlet pipelines or the motor's position.
Can these pumps handle corrosive liquids?
Yes, while the standard material is cast iron, we offer stainless steel and bronze impellers/casings to accommodate various chemical properties of the pumped medium.
What is the difference between mechanical and packing seals?
Packing seals are cost-effective and easy to replace but allow for slight controlled leakage for lubrication. Mechanical seals are more durable and provide a nearly leak-free solution for sensitive environments.
What driving options are available?
The SOW series can be driven by either high-efficiency electric motors or diesel engines, depending on the site requirements and power availability.
Are the pumps compliant with international standards?
Yes, the SOW series pumps are designed and manufactured to meet ISO2548C, GB3216C, and GB/T5657 standards for centrifugal pumps.
What is the maximum operating pressure?
Standard models support up to 1.6Mpa. However, special configurations are available that can support operating pressures up to 2.5Mpa.
