FM ELECTRIC PUMP 27KG 24VDC 85737

The LINCOLN FlowMaster II (Model 85737) was designed for industrial central lubrication applications where continuous and controlled grease transport is required. With a 24 V DC drive, internal speed control, and a robust, positive displacement pump construction, the 85737 is a practical choice for maintenance teams needing reliability and ease of installation. 

Technical Details (Core Specifications)

• Product Name / Model: LINCOLN FlowMaster II, 85737. 

• Power Supply: 24 V DC (range 18–32 V).

• Motor Power: 1/3 HP (≈0.25 kW) with built-in speed control. 

• Reservoir / Compatibility: For 60 lb (≈27 kg) reservoir (model version suitable for 27 kg). 

• Gear Ratio: 19:1, 2-stage (lower power consumption, adjustable gear sets possible). 

• Discharge Per Pump Cycle: ≈0.07 in³ (≈1.15 cm³) — flow ≈57 cm³/min @ 50 rpm / 114 cm³/min @ 100 rpm (tested with NLGI-2 grease at 68 bar). 

• Connection: 1/4" NPTF outlet. 

• Operating Temperature: −40 °F to +150 °F (−40 °C to +65 °C). 

• Electrical Performance: current curves and fuse recommendations in manual (see table in data sheet). 

• Note Operating Pressure: maximum specifications vary by configuration — follow the manual; some documentation provides examples up to 5,000 psi standby range but the manufacturer also warns not to exceed maximum outlet pressure (brand-dependent limits, see manual). 

Applications

• Single-line parallel and single-line progressive lubrication systems. 

• Central lubrication for fleets and heavy equipment, production lines, and mobile equipment with 24 V power supply.

• Ideal where programmed, automatic lube cycles are required in conjunction with injectors or SL series injectors.

Benefits and Features

• Guaranteed Continuity: positive displacement, double acting — delivers during up and down strokes. 

• Energy Efficient: 19:1 gear ratio reduces power consumption under resistance. 

• Adjustable Speed: built-in motor speed control (can be reduced by up to 10% of maximum speed) for flow fine-tuning. 
  

• Easy Installation & Maintenance: NPT outlet, integrated vent/relief valve, and availability of interchangeable gear sets and service components.
