The Bio-Chem Valve™ Solenoid Operated Micro-Pump is a solenoid operated device designed to provide a precise, repeatable and discrete dispensed volume of fluid. The pumps use a flexible diaphragm to isolate the solenoid actuation mechanism from the fluid path (read more on micro-pump valve operation).

Bio-Chem Valve™ Solenoid Operated Micro-Pumps are particularly suitable for use in highly aggressive and / or high purity fluid applications such as analytical chemistry and clinical diagnostics. (Download brochure – Solenoid Operated Micro-Pumps).

Features of the Solenoid Operated Micro-Pump:

• 12 volt or 24 volt DC solenoid
• Choice of pump style
• Threaded ports: Available dispense volumes; 20µl, 30µl, 40µl, 50µl, 60µl, 100µl, 125µl, 150µl, 175µl, 200µl, 225µl, 250µl
• Manifold mount: Available dispense volumes; 20µl, 30µl, 40µl, 50µl, 60µl
• Inert fluid path with only three wetted components (body, diaphragm and check valve) made entirely from chemically inert materials
• Choice of materials -(read more - Plastics & Polymers Reference Page)
  • Body materials:  PTFE, PEEK, PPS & POM
  • Diaphragm materials:  PTFE, EPDM
  • Check valve materials: EPDM, FKM, FFKM
• Self-priming – At start-up, pumps are able to draw air. The suction created by the pumps is sufficient to pull liquids from an unpressurized container located up to 1.3m beneath the pump.
