Batch Plant Pump Guide

    28th April 16

Australian Pump, working with leading concrete companies, has put together a batch plant pump selector. Aimed at improving reliability and cutting maintenance costs, the guide identifies the correct pumps for the various stages of water recycling.

“The abrasive nature of batch water means that pump selection is key to improved plant efficiency,” said Aussie Pumps Neil Bennett. “Our extensive research into these plants has resulted in an easy to use guide that takes the mystery out of pump selection,” he said.

When recycling grey water the pumps must be able to handle cementitious laden liquids with stones and grit mixed in. The Tsurumi range of KTZ dewatering and slurry pumps are designed specifically for this type of application.

Tsurumi Pump is the world’s leading manufacturer of submersible pumps with an annual manufacturing capability of over 1.4 million pumps. With over ninety years’ experience they have developed a comprehensive range of robust, super-efficient pumps for use in concrete batch plants.

The KTZ series incorporate wear resistant hi chrome iron impellers that enable solids in suspension to pass smoothly through the pumps.

“Reliability is a real cost saver for batch plants. These pumps are built to withstand abrasive conditions therefore they work better and last longer,” he said. ”We’ve found many instances where cast iron sewage pumps, suited to passing soft compressible solids, have literally been eroded away by the sand and grit. The KTZ series means there is no need to compromise and use unsuitable pumps,” he said.

First Flush & Wedge Pit Pumps

These pits collect grey and sand laden water. Although settled, this water can still be abrasive so the KTZ pumps with their hi chrome iron internal parts are ideal for recycling it into the batch.

Submersible pumps self-prime and can be used with flexible discharge pipes. This makes the system easy to install and remove when the pits need to be excavated. The pumps self-flush which switched off thus preventing clogging due to settling solids.

Stirrer Pits

This water has a high cementitious content and sometimes highly abrasive slag. The KTZ series can handle solids up to 8mm without issue and again their wear resistance capability means the pumps last longer than cast iron equivalents.

Batch Water Tanks & Slump Stand

The KTZ series offer capacities of up to 2,400 litres per minute flow, and heads as high as 48 metres.  This means loading batch water from the holding tanks is fast, cutting the waiting times for trucks at the hoppers and slump stands. 2”, 3” & 4” pump configurations are available to suit the existing pipework.

Emergency Back Up

“We’ve found a lot of misapplied pumps in ready mix plants around the country,” said Bennett. “Failure rates for these pumps are high and when a pump is down time it’s costing money and productivity,” he said.

The Tsurumi HSD slurry pump is ideal for emergency deployment. This portable, single phase ‘plug and go’ pump can be thrown into a pit quickly if a pump goes down or in a flood situation where solids contaminated water needs to be moved.

The HSD pump has a hi chrome impeller and built in agitator to move silt and sand. It can be supplied as a manual pump or with a float controlled auto on/off function.

“Tsurumi have made their name supplying pumps for the concrete industry around the world,” said Bennett. “We want Australian plants to get the cost cutting benefits these pumps bring,” he said.
