• Accurate and consistent output with adjustable flow rates

• Corrosion-resistant construction for tough environments

• ±3% dosing accuracy, unaffected by backpressure

• Modular design for easy maintenance

• Temperature range: –20°C to +150°C

Material of Construction (MOC):

• Stainless Steel: SS304, SS304L, SS316, SS316L

• Special Alloys: Hastelloy C, Alloy-20

• Gland Sealing: PTFE

• Custom alloys available on request

Options:

• Jacketed Head – For heating or cooling process fluids

• Auto Flow Control – 4–20 mA input for remote control

• Multi-Head Design – Different outputs with one drive

• Modular Setup – Simplex, Duplex, Triplex, or Quadruplex

Notes:

• As flow increases, pressure decreases.

• Final pump selection is determined by Minimax Dosing Pumps based on customer requirements.
