World Chemical magnetic drive submersible pump
The GWN magnetic drive submersible chemical pump utilises carbon fibre reinforced polypropylene (CFR PP) for the main pump body, and silicon carbide, high purity ceramics and PTFE for critical parts. No metal is in contact with the pumped media resulting in the GWN pump being compatible with strong acidic and alkaline solutions.
Design of submersible chemical pump
The GWN has been designed with a ‘disk type magnet drive system’ and therefore does not include oil-bath mechanical seals that are typical of general submersible chemical pumps, eliminating the potential risk of oil leakage & contamination due to wear of the mechanical seal.
Supplied with a H-type motor as standard meaning the GWN is compatible with liquids up to 75ºC and easily handles liquids with difficult characteristics such as foaming.
The GWN range offers transfer volumes up to 19.8m3/hr.

Frequently asked questions

Every type of should have a maintenance program that will ensure its operational life is as long as possible. A should include regular inspections and services to help maintain the pump’s performance levels. If a chemical pump is a critical part of your operation, a spare should be kept on hand so that any downtime due to pump failure is minimised. We can offer a maintenance and service package with any of our chemical pumps.

A chemical resistant submersible pump’s operational life depends on the application. Applications involving strong acids, alkali or liquids with solids such as slurries in arduous conditions are significantly more demanding than one pumping a neutral liquid at an ambient temperature. You can contact our helpful team and we will work with you to understand your application and specify the right submersible pump.
-
The liquid enters the chemical resistant submersible pump through a filter at the bottom, which typically rests directly on the floor of the tank or sump. The internal mechanics of the magnetic seal, motor and impeller work in unison to drive the liquid out of the pump discharge and through the connecting pipework.
Some chemical resistant submersible pumps use mechanical seals, but the World Chemical Submersible pump contains a disk-style magnetic drive system which removes the need for a mechanical seal. This technology means a seal barrier fluid (usually oil) is not required, so there’s no chance of oil leakage from the seal which could potentially cause contamination. A vertical pump is capable of transferring liquids out of a tank or sump, but in this type of pump the motor sits above the liquid level. For details of our Vertical Pumps see here.

We supply World Chemical Chemical Resistant Submersible Pumps, which are specifically designed to work with aggressive and corrosive chemicals in challenging applications. The pump works by being completely submerged under the liquid it is transferring, with the pump sitting on the floor of the tank or sump of liquid.
Spares and service
To help you get the most out of your fluid transfer solutions, we hold significant stock of a broad range of pump spares kits and spare parts, as well as offering routine maintenance, repairs, and priority services.
