Bracket & Lubrication Options for Double Suction Split Case Pumps

The double suction split case pump relies on a well-engineered bracket system to maintain stability, support the rotor, and ensure long-term operational efficiency. Brackets are available in several configurations—thin oil lubrication, grease lubrication, and barrel brackets—each designed to meet different application and performance requirements. This article explains the design features, component structures, and selection criteria to help you choose the most suitable bracket system for your double suction split case pumps.

Bracket Types and Key Components

Bracket Type	Key Components
Thin Oil Lubrication Bracket	Bracket body & cover, Shaft, Bearing box & bearings, Bearing gland, Retaining sleeve, Lock nut, Oil seal, Water retaining plate, Dismantling ring
Grease Lubrication Bracket	Transparent inspection cover, Lubrication cup, Bearings (directly greased), No water cooling device
Barrel Bracket (For Low-Power Pumps)	Bracket body, Bearing housing, Shaft, Bearings, Bearing top sleeve, Bearing gland, Oil seal, Oil cup, Water retaining plate, Dismantling ring
Available Specifications (Barrel Bracket)	T200ZJ-I-A70, T200ZJ-I-A60, T150ZJ-I-A60

Bracket Types and Application Advantages

Bracket Type	Application Advantages / Features
Thin Oil Lubrication Bracket	Excellent cooling and lubrication; suitable for continuous operation; reduces bearing wear and vibration; ideal for medium to large high-power pumps
Grease Lubrication Bracket	Simplified structure and easier maintenance; suitable for low-maintenance applications; eliminates oil circulation system; suitable for medium-performance pumps
Barrel Bracket	Compact and reliable; designed for small pumps (200ZJ and below); cost-effective; suitable for light to moderate operational loads

How to Select the Right Bracket

Bracket Type	Selection Guidelines / Suitable Conditions
Thin Oil Lubrication Bracket	Best for high-performance or continuous operation; large, high-power double suction pumps; provides superior cooling and bearing protection
Grease Lubrication Bracket	Suitable for medium-duty applications; low-maintenance requirements; recommended when oil circulation systems are impractical
Barrel Bracket	Designed for small, low-power pumps; cost-effective and reliable for light to moderate applications

Conclusion

Understanding the differences between thin oil, grease, and barrel brackets helps ensure your double suction split case pump operates with maximum stability, efficiency, and durability. By selecting the correct bracket type based on load conditions, power requirements, and maintenance preferences, you can significantly enhance pump reliability and reduce long-term operational costs.
