Pumping Particles is No Problem

October 25, 2022 | Categories: Food - Opinion Piece | by

Pumps are an integral part of many food processing facilities, but care must be taken to select the correct pump for both the product being moved and the process requirements. Physical damage to the product, as well as the influence of factors such as pressure and shear stress must all be taken into account. When you wish to pump large solid items, such as fruit and vegetables, these challenges become even greater.

 

There are many types of pump on the market, including rotary lobe, rotary piston, reciprocating positive displacement, progressing cavity, peristaltic hose and air-operated double diaphragm designs. However, not all of them are capable of maintaining product quality at a reasonable cost while keeping the required pressure in the system.

Furthermore, traditional pumps can be expensive to maintain while lobe pumps have low flow rates.

To overcome these difficulties, HRS developed the BP Series of hygienic reciprocating, positive-displacement pumps, which are suitable for a wide range of difficult to handle food products, including whole peppers, strawberries and baby carrots, as well as sauces, dips, fruit purées, and many others.

Positive displacement pumps have an expanding cavity on the suction side of the pump and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and is forced out of the discharge side as the cavity collapses.

Over the years three additional models have been added to the BP Series range:

  • BPM Series – a skid-mounted, mobile version allowing it to be used across multiple production lines
  • BPSC Series – designed for highly viscous products, and those which are produced and packed at low temperatures, it features a screw conveyor to feed the pump inlet
  • BPH Series – a horizontal version with a vertical inlet and a ball valve instead of a clap valve

If you have experienced product issues using other pumps, then chances are the HRS BP Series will be able to meet the challenge whether processing whole fruits or vegetables, delicate dairy products like creams and sauces, highly viscous materials such as humous, or larger particles such as coleslaw or fruit compote.
