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 (in particular, progressive cavity pumps can break the product, while double diaphragm pumps result
umps are an integral part of many food processing facilities, but care must be taken to select the correct
in a low pressure drop). 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. The HRS BP Series Piston Pump is operated either hydraulically or pneumatically (depending on available air supply pressure), and incorporates a separator fitted between the piston and the hydraulic chamber to ensure that there is no contact between the product chamber and the hydraulic oil (if fitted). The standard BP Series has an
adjustable flow rate of between a minimum of 200 litres/hour and a maximum of 12,000 litres/hour, and features a high pressure drop of up to 30 bar. It is suitable for a wide range of high viscosity, shear sensitive and large particle-containing fluids. Clap valves allow
The BPM Series is a skid-mounted, mobile version allowing it to be used across multiple production lines
