What is vertical slurry pump?

1.SIMPLE INSTALLATION

With small vertical sump pumps is it possible to hang the pump in the sump by the lifting bracket provided. Larger units are normally bolted to a permanent base plate. Pump bearings are in a housing above the base plate for accessibility and protection.

All pumps can run dry intermittently. Pumps with metal pump parts can run dry for an unlimited length of time. Special designs giving extended length, with the bearings below the base plate, are available on request.

2.ROBUST DESIGN

The heavy-duty pump shaft is of cantilever design, hanging below the bearing housing. There are no submerged bearings, stuffing box or shaft seals. This design ensures minimum maintenance and eliminates the need for water flushing.

The pump shaft is mounted in grease lubricated roller bearings. Impeller clearance is maintained by external axial adjustment of the shaft/bearing assembly. Bearings have double seal protection against contamination.

3.HIGH-QUALITY PARTS

Standard pumps are supplied with parts in wear resistant natural rubber or High Chrome white iron alloy, with a nominal hardness of 600 BHN. Other wear part materials available include elastomers in synthetic rubbers and polyurethane and metals such as 316 stainless steel and CD4MCu. Parts in different materials are fully interchangeable and can be combined for optimum life.

4.WET END

The “wet end” parts have large material sections for extra-long wear life and are designed for the toughest of applications. Single volute and generous solids passage through the pump ensure safe and clogless operation. The “wet end” assembly is suspended from a tubular column below the bearing housing.

5.DRIVE

Pumps can be supplied with a V-belt drive, motor and drive guard. The motor is mounted vertically on an adjustable motor plate fitted beside the bearing housing.

6.MOTOR SIZE

Motor size and V-belt drive vary with the pump application. Minimum data required for an approximate pump, speed and drive motor selection are:

• Slurry flow rate
• Slurry density
• Total discharge head
