Constructional features:

Pump casing / cover

The casing is executed as a single volute with tangential discharge.

Wear rings

The casing and cover and supplied with renewable axial wearrings.
Optional, impeller wearings can be supplied.

Impeller

The closed impeller is mounted with a key to the shaft and locked by an impeller screw. For reducing the pressure behind the impeller balancing holes are drilled. No balancing holes will be drilled by application of a suction to avoid air entrance via the pump bearing.

Bearing arrangement

–  Top bearing
The bearing bracket is executed with radial and axial ball bearings.
The bearings are grease lubricated and they can be re-lubricated by a grease nipple on the bearing housing.

–  Pump bearing and intermediate bearings
The pump bearing and intermediate bearings are executed as plain bearing. Lubrication method by product, grease or external fluid.

Shaft sealing

–  Standard execution
Due to the design with the separate discharge pipe a shaft sealing against the pumped medium is in  principle not required.

–  Shaft sealing variants
An execution with several shaft sealings for gastight execution is possible and will be used in application as:

• Toxic gassing fluids
• Fluids with explosive dangerous gasses
• Overpressure in the tank
• Bad smelling fluids
• Hazardous liquids

Possible options as packed gland, double lipseals or mechanical seal are available

Baseplate & discharge pipe

The baseplate is standard supplied with rectangular baseplate optionally flanged (round) baseplate available.
The discharge pipe have EN1029 PN10 flange as standard and optional ANSI16.5 150#

Strainer

Strainer is used to protect the pump against particles from the medium. The strainer baskets are constructed from perforated (stainless) steelplate (openings 5x5mm).

Extended suction pipe
Possibility for extended suction pipe construction. This results in a larger immersion suction depth and  can also lead to lower purchase costs.
