Product Range
Goodwin slurry pumps come with four sizes of motor and four types of wet end. The pumps come in three outlet sizes. This gives a range of pumping performance to suit any slurry pumping application. The pumps are open vane single stage pumps.
Goodwin high head dirty water pumps come with two sizes of motor. They are closed vane multiple stage pumps designed to create a high pressure.
Goodwin has developed the Super Duplex Stainless Steel “SDSS” acid resistant slurry pump. Constructed with all slurry contact parts made from corrosion resistant alloys, these pumps will reliably operate where other pumps will rapidly fail. They are open vane single stage units.
Goodwin submersible pumps have been manufactured since 1982 and are recognised as market leaders in terms of performance and reliability.
The pumps have been continually developed over four decades to enhance strength and endurance. Goodwin pumps deliver proven performance in the most demanding environments.

Goodwin can supply a range of cables specially selected and tested for use with slurry pumps. For 100 size pumps cable is supplied with galvanised steel armouring to protect against damage. The IP68 rated cable gland seals against both the inner and outer sheaths, so even if the outer sheath is damaged water cannot ingress to the electrical connections.
High temperature winding materials allow the pump to operate reliably even when media temperatures are over 90°C.
The Goodwin pump uses high quality brass end rings and bars in the rotor that are brazed together. Brazed brass construction is proven as being more robust and reliable than die cast alternatives when the pumps are subjected to high energy Direct On Line (DOL) starts.
The Goodwin pump motor runs submerged in oil that lubricates and cools the bearings and the mechanical seal. The oil dissipates heat from the hottest part of the motor to the high mass stator housing that acts as a heat sink, eliminating motor hot spots which can give premature motor winding failure.
The Goodwin pump benefits from forced convection cooling by nature of the pumped fluid passing around the motor housing before it leaves the pump. This allows the pump to run for extended periods of time even if it is run semi-submerged. This is an integral part of the design and makes the requirement of additional motor cooling unnecessary.
To balance the load on the pump shaft, bearings and mechanical seal, Goodwin use a twin volute casing, reducing vibration and extending the life of all component parts especially the mechanical seal.
Generously oversized to give extended life when pumping high specific gravity slurries.
The wet end of all Goodwin slurry pumps are made of NiHard alloy. For very abrasive applications Goodwin can offer tungsten carbide coated impellers, inducers and wear plates as it is possible to coat 100% of the rotating surface exposed to the slurry and thus provide the customer with excellent component life. Closed vane impeller designs have surfaces which can’t be tungsten carbide coated. 150 and 200 size slurry pumps have tungsten carbide coated wet end parts as standard. For 100 size pumps, coating is optional.
This feature assists the breakdown of large particles in the impeller that might ultimately lead to a blocked pump. There is little if any chance of the impeller becoming blocked as opposed to closed vane impellers which are often blocked and tend to stay blocked.
To reduce the bending moment on the shaft, when it comes into contact with large particles, the Goodwin inducer is kept as close as possible to the lower bearing.

The 150 and 200mm Goodwin Pumps are supplied with a removable and replaceable discharge elbow made from precipitation hardened Stainless Steel.
Suitable for submergence depth up to 28 metres as standard. The Goodwin mechanical seal is only subjected to the pressure from the submergence depth of the pump which generally is only a few metres of head and not the discharge pressure of the product. This greatly reduces the chance of fluid ingress into the motor itself and the destructive consequences which can result. The seal is positioned directly below the lower bearing to give it maximum support and protection from vibration.
