Wet-End Spares Kit




To assist our customers, Goodwin have developed a "Wet-End" spares kit which includes all of the necessary items your technicians will need to perform essential periodic maintenance on your Goodwin pump, to ensure reliable operation and the long life of your investment.

Control Panels




Panels will meet and exceed MDG15 and we can also produce bespoke panels to customers requirements

The Goodwin fully automatic control panel has four main modes of operation:


  • 1Manual mode
  • The operator can Start and Stop the pump as required.

  • 2Automatic with Float switch start
  • When the high level float switch is activated, the pump will start. When the low current relay senses the drop in power, the pump will stop

  • 3Automatic with Timer start
  • When the Start Timer is energised (user defined time), the pump will start. When the low current relay senses the drop in power, the pump will stop.

  • 4Automatic with Float switch & Timer start
  • In this mode, both the high level float switchand the start timer are used. This means that at a pre-determined time the pump will start, but is the slurry level becomes high before this time, the pump will start. When the low current relays senses the drop in power, the pump will stop.

All Goodwin control panels protect against:

  • Earth leakage faults - damage to the cable or pump
  • Current overload - of the pump
  • Phase imbalance - voltage variation of the incoming supply phases
  • Phase rotation - to ensure the pump runs in the correct direction
  • Phase loss - the loss of one or more of the incoming phases
  • Under voltage - if the incoming voltage is too low
  • Over Voltage - if the incoming voltage is too high

The benefits of using a Goodwin fully automatic control panel:

  • The panel can operate in "Manual" mode, where the operator can Start and Stop the pump as required.
  • When used in "Automatic" mode, it extends the life of the pumps wearing parts, as it will not be left running on snore (running but not pumping) for extended periods of time. The Goodwin panel does this by using an electronic low current relay, which detects when the pump is running on a light load (i.e. Snore).
  • Before starting, a Xenon beacon flashes and an audible (100Db) alarm sounds to warn operatives.
  • The panel is fitted with a lockable "isolator" for safe maintenance.
  • The panel has the facility to be connected to a "Remote" Start / Stop station, including an Emergency Stop.
  • The 90kW & 112kW panels can be supplied for either "Direct-On-Line" starting, or with "Soft Start". All 30kW panels are designed for "Direct-On-Line" starting.
  • All panels are IP65 rated as standard, and are suitable for both indoor and outdoor use.
  • All panels are fitted with rear mounting brackets as standard.

Electrical Accessories





Pump Cable

The cable conforms to AS1802:2003, and has a layer of waterproof insulation. The IP68 rated cable gland seals against the outer sheath, to prevent the ingress of fluids into the electrical connections.


The Goodwin range of pumps are supplied with 3 phase + earth armoured trailing cable for maximum protection against accidental damage – adding to the rugged reliability of the Goodwin submersible slurry pump.


This is tried and tested cable that is fitted to the Goodwin pump, and we will NOT supply any other cable between the pump and electrical control panel.


Distances may vary from pump to panel from installation to installation – please specify length of cable to be supplied with pump when ordering. (max cable length between pump and panel is 100m).


The cable comprises of three power cores and three separate earth cores


Each core is composed of multiple stranded circular annealed tinned copper wires complying with the requirements of AS/NZS 1802:2003.


The outer cable protection consists of Chlorinated rubber sheathing which covers heavy duty galvanised steel armour, which in turn covers an inner Chlorinated rubber sheath which protects the three phase conductors and earth conductor. Each of the three phase conductors has its own composite copper screen. The phase insulator is made of EPR, to AS/NZS 1802:2003.


Voltage rating: 1.1/11kV.


Cable Cutaway Cable Cutaway

The durability of our cable and cable gland arrangement is so strong that customers have retrieved pumps by lifting them directly with the cable from a sump.


Goodwin always recommends that proper lifting tackle is utilized at all times and take no responsibility if a cable was to pull out if the pump (over 500kg) was lifted by it.


Alternative cable offered for very light duties.


The cable conforms to AS1802:2003, and has a layer of waterproof insulation. The IP68 rated cable gland seals against the outer sheath, to prevent the ingress of fluids into the electrical connections..




Installation Accessories





Lifting Chains

Custom made lifting chains are recommended so the slurry pump is lifted from a single point. This means that the pump remains vertical at all times, and is not lifted on an angle, which can happen on site if only one of the lifting points is used.

By keeping the pump vertical oil is kept in the correct areas to allow maximum lubrication and heat dissipation, maximising bearing life and motor cooling. Additionally when starting the pump when it is submerged in settled slurry ¯ it allows the pump to kick as described in the hose accessories section.


As it is a submersible pump the shackles and chain unit come in a galvanised finish to minimise corrosion and maximise working life.


The chain unit is supplied with two shackles to couple it directly to the Goodwin pump.

For lifting our submersible slurry pumps we recommend that a hoist with a minimum rating of 1.5 tonnes is used for our 30kW pumps and 5 tonnes for our 90 & 112kW pumps. This is because from our experience, additional lifting force can be required to break the pump free of the settled slurry, which is more than would be expected during normal operation, where only the weight of the pump and pipe work to be considered.




Chain Blocks


Knowing the following information, we will make sure that it is suitable for your installation, by making sure that it will allow the pump to reach the bottom depth required and that the chain loop for raising and lowering the pump only reaches to the ground level where the operator is standing ¯ so there is not excess chain everywhere.


lifting chain

We can source and supply chain lifting blocks for customers who want us to assist with their installations.


Prior to specifying a chain lifting block it is necessary to know the details of the installation:


  • Depth of Pit pump to be lowered into
  • Height Above Pit the block will be suspended from.


Pontoons

The pump can be mounted on a pontoon, which we can custom build to your site requirements. We have a range of modular pontoons available, with interlocking design depending on the number of pumps you have. We can also supply custom built Steel pontoons. Gangways and walkways are available in rigid aluminium or steel, or floating cells to any length required.

Hose and Accessories





Goodwin recommends all its submersible slurry pumps are suspended on chains, with a Bauer type adapter for coupling to the pump followed by a length of reinforced flexible hose before connecting to any rigid pipe work (shown in the photo). This enables the pump to operate correctly when it is in thick heavy slurries, as when the pump is started and slurry has settled around it there is a very high energy start as the motor is direct on line which makes the pump kick.


As the pump is suspended on chains, the "kick" it breaks away from any settled slurry allowing standing water to get to the impeller by flowing around the pump body as it has broken away from the slurry. As soon as this has happened the pumps agitator starts emitting its hydraulic shock wave 'sphere of influence', putting dense particles into suspension to be pumped with ease

Goodwin hoses are supplied with PN16 flanges on both ends as standard.
