2-Series Mini-Pump
The 2-Series Mini-Pumps are low-flow/high-pressure external gear pumps that are completely field repairable. With a ruggedly designed 316 Stainless Steel or Titanium body and several material options for shafts, gears, wear plates and bearings, these pumps can be used in a wide variety of services.

Typical Applications
The 2-Series Mini-Pump is typically used in chemical processing plants, pilot plants, laboratories, paper-making, chemical dosing and metering, and pipeline sampling.

Features:
  • Pulseless flow
  • Flow rates from 1 GPH to 60 GPH
  • Viscosities: 0.3 – 10,000 cP
  • Differential pressures up to 225 PSI
  • Titanium or 316 SS body
  • Low NIPR (NPSHR)
  • Corrosion resistant materials
  • Mag-Drive
  • Self-compensating wear plates limit slip on low viscosity fluids
  • High torque SmCo Magnets
  • Repair Kits available

Maintenance
The 2-Series Mini-Pump was designed with reliability and ease of maintenance in mind. The gear and shafts are permanently fixed to each other making repairs easy and fool-proof. Standard repair kits contain all wearing parts
and static O-Rings:

  • Gear-Shaft Assembly
  • Bearing-Wear Plate Combination
  • O-Rings
Repair Kits Available
Repair Kits simplify inventory and speed repair.
All parts can also be purchased separately.

Every Pump Needs Relief
Positive displacement pumps should be installed with a relief valve in the discharge line. This will protect the pump and piping should a valve be closed inadvertently. Liquiflo manufactures two sizes of relief valves in both 316-SS and Alloy-C for this purpose.
