  • Single piston double effect pump, specially designed to handle particulate products delicately
  • Hydraulically or pneumatically driven
  • Adjustable product flow rate (by adjustment of the hydraulic drive)
  • Large product flow capacity (up to 12 m3/hr)
  • High operating pressure (up to 30 bars)
  • Hygienic design
  • It can handle products containing large particulates. The port size in the biggest pump is 75 mm diameter
  • The separator between the pump body and the cylinder prevents the product chamber from being contaminated
  • Perfect response to CIP
  • Self priming and will draw the product from the storage vessel
  • Total respect to integrity and shape of the product
  • The hygienic design combined with a perfect response to CIP cleaning makes this pump so suited to food processing applications where product integrity and shape must be guaranteed, to maintain both appearance and nutritional quality
  • Hygienic design. The separator is purged with steam
  • Frequency variator
  • Actuated ball valves
  • Spring valves
  • Damper at the outlet to avoid flow fluctuations
  • The HRS Piston Pump is of a completely hygienic design, and incorporates a separator fitted between the pump and the hydraulic chamber to ensure that there is no contact between the product and hydraulic oil
  • The pump range is manufactured from AISI 316 stainless steel and designed for low maintenance. It has an adjustable flow, which can range from a minimum of 160 lph to a maximum of 12,000 lph, and features a high-pressure drop of up to 30 bars. The HRS Hygienic Piston Pump is capable of high working temperatures of up to 100°C and can operate both under vacuum or empty of product. In addition to its delicate handling facility, this large capacity (up to 12 m3/hr) pump is also able to handle large particulates, due to its 3″ inlet and outlet ports

Design conditions:

  • Design temperature 120°C
  • Component thicknesses and/or connection ratings may be varied for specific applications

Construction

Materials:

All product wetted components manufactured from AISI-316 stainless steel.

Connections:

  • ISO Clamps

Surface finish:

  • Product wetted zones: N4 lapped
  • Externally: glass blasted or polished. Welds are pickled and passivated
  • Does not break the product
  • Delivers high flow rates (up to 12 m3/hr)

  • Allows high-pressure losses (30 bar)
  • Can work under vacuum
  • Is self-priming
  • Can work empty (without product)
  • Requires few spare parts
  • Has no rubber in contact with the product
  • Can work at high temperatures (100°C)
  • Adjustable flow
  • Traditional pumping systems for particulate products have always been a daily problem for all processors who need to move or pump whole or diced fruits or vegetables. Problems caused by the high cost of triplex piston pumps, the poor efficiency of lobe pumps, the damaged product resulting from the use of screw pumps, or the low pressure losses which double diaphragm pumps need
  • The ideal process pump for whole fruits and vegetables, leaves, strips, slices, dices, slivers… and to guarantee no product breakage
  • Fruit and vegetable: dices particulates, pudding rice, cream mixes
  • Ready-to-eat foods
  • Juices/ beverages with dices, fruit sacs
  • Special dairy based foods
  • Nutraceutical & fortified foods
