Impeller pump for petrochemical process WEIR Oil Gas

Heavy duty process horizontal pumps, radial split, centerline supported, single entry overhung impeller.

Pump components geometry optimised through hydraulic, structural, thermal and dynamic F.E.M. analysis lead to an high product reliability.
Back pull-out construction for easy maintenance procedures.
Choice of multiple impellers for optimum efficiency over a wide operating range. Coverage consists of more than 100 different hydraulics.
Twin volute configuration to minimise radial loads and shaft deflections (over 2" discharge nozzle size).
Centerline feet mounting for high temperature stability.
Bearing bracket geometry optimised in order to definitely eliminate water cooling system, even for high temperature applications (400°C).
Casing, bearing frame and baseplate enough stiff to assure minimum shaft deflections under heavy nozzle load conditions (extended life for seal and bearing).
Wear rings and balance holes optimised for an extended life under the most adverse suction conditions (duplex angular contact or roller thrust bearings applicable).
Bearing housing intrinsically contamination free, even in case of mechanical seal failure.
A wide range of sizes and material combinations complete the variety of the offered product.
