HpE Graco SaniForce Piston Pumps

Graco Piston Pump

American pump giant Graco’s vast line of sanitary, piston pumps move extremely difficult materials that others can not.

Dominant in food factories, but also employed in the pharmaceutical and cosmetics industries, these popular pumps are ideal for medium to high viscosity materials.

Piston pumps benefit from the following qualities:

  • Flexibility
  • The air motors improve serviceability and increase efficiency and are therefore of low cost to the customer
  • The easily dismantled lowers are made with 300 series stainless steel for long-lasting durability
  • They have pressure ratios up to 12:1
  • The flow range is from 4 to 14 GPM
  • Siphon up to 5,000 cps and 100,000 cps if immersed
  • Double-ball or priming piston designs
  • Drum length and stubby options available
  • Can be combined with Graco’s drum or euro bin follower plates to get the very last drop of liquid from those portable containers

HpE Altech Piston Diaphragm Pump

Altech Piston Diaphragm Pump

This high performance dosing pump from Altech can be used on very viscous media such as lecithin and emulsifiers. These pumps are modular built and inter-changeable, allowing for high flexibility with different pump features being able to be combined.

Set-up of the pump is straightforward, involving a quick exchange of the diaphragm. After the piston flange is dismantled there is no zero-resetting.

Benefits of the pump are as follows:

  • Robust and reliable construction
  • Minimum amount of spare parts required due to highly efficient design
  • Quick and easy setup of a twin pump by installing a second dosing unit (with the same or a different capacity) onto the driving gear
  • Symmetric design allows the piston flange to be mounted on either side of the dosing units
  • Simple conversion. By adding four stud bolts, the metering pump can be converted from manual to electric stroke length control
  • For operation, high standard multi-range motors (220-240/380-420 V, 50/60 Hz) are used for a wide range of applications and short delivery times for all pump types
  • Integrated safety pressure relief valves (test certified by TÜV) are standard for all our pumps which protect the pump in the event of overpressure or cavitation.
