Large winery installs Vaughan self priming chopper pump to solve clogging problems

Pump Systems Ltd have recently supplied a Vaughan self-priming chopper pump to a large New Zealand wine company for pumping wastewater containing solids such as leaves, bottle tops, string, plastic caps and strapping. This material caused continual clogging problems for the existing pumps, requiring suction screens that would also clog and get 'blanketed' with leaves and other debris. Installation of the Vaughan chopper pump eliminated all of these problems.

The Vaughan name is widely becoming accepted as the ultimate solution for solving difficult solids handling pumping problems in both municipal and industrial processing environments. The newly introduced self-priming range utilises the same proven and patented design of other Vaughan chopper pumps with a hardened impeller, cutter bar and upper cutter, allowing the pump to chop and pump solids laden waste material without the risk of clogging.

Tecnicapompe screw impeller pumps offer gentle solids handling for pumping delicate products

Four model HCD 055 screw impeller centrifugal pumps have recently been supplied to a customer who requires pumps with the ability to transfer water containing fine soft solids. The key to their process is to obtain a flow rate with a gentle low shear pumping action to preserve the original features of the transferred media. The special shape of the HCD screw impeller enables the centrifugal pump to transfer solids without any damage to the product and without the risk of clogging the pump.

Manufactured by Tecnicapompe (Italy), the HCD and ZCD screw impeller centrifugal pump is available in many different sizes and versions for flow rates up to 1,400 m3/h and heads up to 30 metres. The pump will handle solids up to a maximum size 100 mm and will withstand operating temperatures up to 120 degrees Celsius. These innovative screw impeller centrifugal pumps can be used with a wide variety of thick products up to 1000 centipoise or with products that have solid particles in suspension of up to 60% solids and 40% water.

Difficult casings application requires heavy duty Vaughan chopper pump to handle stringy solids

A Vaughan vertical wet well chopper pump was recently supplied to a large processing company in New Zealand for pumping wastewater containing sheep casings, mucosa, slime, threads and intestines. Material of this nature is notoriously difficult to pump, as most pumps will not cope due to clogging and binding of impellers and shafts. Pump Systems Ltd were able to offer the perfect solution with the patented chopping action of a Vaughan chopper pump.

The unique configuration of a Vaughan chopper pump means that the sharpened impeller blades meet with the arms on the cutter bar to effectively chop material as it enters the suction. In this case, to prevent stringy material from wrapping behind the impeller, which is particularly important when pumping casings, the upper cutter was finely positioned with minimum clearances to shred and remove any stray solids that enter the mechanical seal area.
