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.

Electrical Accessories





Pump Cable

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 four power cores (3 phase + Earth)


Each core is composed of multiple stranded circular annealed tinned copper wires complying with the requirements of BS 6360.


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, covering a nylon braid. The phase insulator is made of EPR, to BS 7655.


Voltage rating:  640/1100 volt cable to BS 6708:1977 and BC Specification 504:1981.


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.



Panel Stand

The Goodwin pump control panel comes as standards with mounting brackets allowing it to be easily affixed to a wall. Should the installation be where there is no-where where the panel can be bolted to we also make a self standing panel stand allowing for flexibility where the pump is installed.


Panel Stand


Panel Shelter

Panel Shelter

In most installations it will not be necessary to cover the pump control panel, but in installations where it could be exposed we make a cover that easily fixes onto the panel providing it with shelter if it is in a exposed location. Covers are regularly installed when the pump is mounted on panel stands, on pontoons due to the exposed location of the panel and in dirty areas, for example when a pump is installed underneath a transfer conveyor on a clean up duty

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, maximizing 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 galvanized finish to minimize corrosion and maximize 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

When pumping from a pontoon we have good experience with several designs ¯ our favoured is a modular system of floating cubes which can be assembled together quickly allowing, allowing for easy installation and transportation if the pontoon is ever required to be moved.


The net result is that you can have a customizable work platform, that is easily created which can vary in size depending upon your application, for example it can be made to hold several pumps if the application requires it without the need for special one-off fabrication costs.

Depending on your application you may want to add floats to your discharge hose.

We can supply discharge hose floats that can be affixed around the discharge hose, floating the hose and making it visible to highlighting its presence to other people.

Control Panels

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.

Protection: read more

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

Benefits: read more

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.

Optional accessories for your Goodwin fully automatic control panel

  • Control panel stand
  • Control panel hood
