Construction Features
Shaft & Bearing
- Heavy-duty shaft design for minimum deflection.
- Maximum 0.05 mm deflection at the stuffing box under maximum load.
- Large-capacity oil sump improves heat transfer, keeps bearings cooler and extends bearing life.
- Arrangement for the semi-open impeller enables front-clearance adjustment for optimum hydraulic performance.
- O-ring seal between the bearing housing and lantern prevents lubricating-oil leakage.
Volute Casing
- Centre-line discharge volute with fluoropolymer-lined construction provides pressure capability, efficiency and smooth media transfer from the impeller to delivery.
- Thick-wall polymer moulded inside metal armour provides strong support at high temperatures.
- Top-discharge, self-venting, back pull-out design.
- Optimum hydraulic design.
- Drain-plug provision allows easy, safe drainage and helps maximize pump life.
Impeller
- Hydraulically optimized semi-open radial impeller.
- Axial forces are balanced by balancing holes and back vanes.
- Reverse locking of impeller and shaft prevents loosening from incorrect rotation and ensures maximum torque transmission.
