Overview
Unlike conventional sealed centrifugal pumps, the hydraulic radial and axial thrust loads must be absorbed internally by a magnetic drive pump. The UCR Series is engineered to reduce these radial and axial loads to a minimum, in order to maximize the wear life of components. Finish Thompson uses a variety of housing styles to help control radial load. The method chosen is dependent upon the pump’s internal design and each work equally well.
The liquid enters the pump at suction pressure and is accelerated in the impeller. Some of the pressurized liquid flows to the rear of the impeller and proceeds through an annular orifice between the inner magnetic drive bore and a stationary sealing ring in the barrier.
After exiting the orifice, the flow splits, with some going through the bushing to the pump suction, keeping the bushing lubricated. The remainder flows through impeller balance holes (some models) to the pump suction.
This stabilized, forward-thrust design allows full curve reliability without compromising pump life.
Impeller is molded as one piece and securely mounted to the inner drive magnet with a locking mechanism, which allows replacement in the field.
- Eliminates need to purchase expensive single-piece impeller magnet assembly.
- Allows impeller diameter to be changed at a lower cost.
- Impeller thrust ring is field replaceable.
- Allows a pump end to be converted to fit multiple applications.
- All frame sizes feature dynamically balanced outer drive assembly fitted securely to the shaft adapter with four bolts.
- Single drive fits multiple-motor shaft adapters.
- Adapters are machined to fit each motor shaft diameter.
- All shaft adapters feature Easy Set Drive and alignment studs for assembly.
- Easily identifiable, multiple pole drive magnets match strength to motor power, reducing cost.
- Motor adapter fits multiple frame sizes.
- Eliminates the need for specialized individual motor adapter flanges.
- Simplifies installation and inventory.
- Optional bronze ring makes it suitable for hazardous areas and is ATEX-certified, providing maximum safety.
- Two jack screws facilitate assembly and disassembly.
- Top mounting pad allows for vibration/IOT monitor attachment.
- Standard ½” (12.7mm) NPT drain/instrument port with stainless steel plug. Allows for drainage/leak detection with customer-supplied conductivity probe.
