Lifting Chains and Chain Blocks
|
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.
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.

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.
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.
