Two special ABEL HP pumps supplied for high pressure cleaning at wastewater treatment plant

Two custom-built ABEL HP-K-25 heavy duty high pressure piston pumps from Germany were supplied to a wastewater treatment plant in the North Island for cleaning wastewater screening equipment. Each pump is designed to deliver a flow rate of 250 litres per minute at a pressure of 5000 kPa, and are fitted with 30 kW, 4-pole speed electric motors driving the pump via a gear box.

Each pump is fitted with a strainer on the suction side, as well as a factory set pressure relief bypass valve on the discharge side to protect the pump. The two pumps have been supplied in nodular cast iron materials with Chromoxide coated stainless steel plungers and stainless steel stuffing box barrels. ABEL HP series pumps are also available in a wide range of material options such as stainless steel and duplex stainless steel materials.

Vaughan chopper pump handles turkey feathers and provides increased efficiency at processing plant

A large poultry processing company in New Zealand was looking for a way to transfer turkey feathers to their rendering plant. Their existing system was mechanically troublesome, messy, and caused continual odour problems. Approximately 1.5 tonnes per hour of turkey feathers are processed daily and the feathers can reach up to 350 mm long with quill diameters up to 8 mm.

To solve this problem, Pump Systems Ltd designed a new sump and flume system where the high concentration of turkey feathers and water would be channeled directly into the suction of a Vaughan chopper pump. From here, the product is chopped and pumped to a feather screen located near the rendering plant and the screened water returned so that it can be recycled. The new system has proven to be clean, easy to maintain, and much more efficient than the previous system.

Custom built Micropump supplied in special materials for corrosive acid application

This interesting project was for the supply of a custom built Micropump to a large chemical manufacturing company in New Zealand for pumping Peroxymonosulfuric Acid, better know as Caro's Acid, which is a corrosive, hazardous and highly reactive chemical. As the exclusive distributor for Micropump in New Zealand, Pump Systems Ltd were able to offer this precise fluid control technology from a market leader in sealless, low-flow gear pumps.

To meet process requirements, the selected Series 5500 Micropump would need to be run at very slow speeds (400 to 800 rpm) to produce flows ranging from 4 up to 10 litres per minute at a differential pressure of 2.5 bar. The pump was supplied in all Hastelloy C-276 body construction, with Teflon gears and static seals to offer excellent corrosion resistance to Sulfuric Acid and Hydrogen Peroxide, both of which make up part of the preparation.
