Prelub P1K System

A pre-lubrication & evacuation system intended for engines of 2 to 6 l displacement or sump capacities of 4 to 28 quarts. Models available for 12 V systems.

Performance (12 V Systems):
23.9° C 15W-40 Oil: 3-35 gpm @ 25-30 A depending on available engine port sizes.
32° 15W-40 Oil: 0.8-1.3 gpm @ 30-40 A depending on available engine port sizes.

Components & Features:

• Permanent Magnet DC Motor: Insulated Ground – improves reliability vs. case grounded motor. High power rise, better maintains flow rate at lower fluid temperatures and higher pressures.
• Pump: High-strength aluminium housing with steel gears and a seal-protection feature that, in conjunction with a circuit breaker, prevents motor damage due to excessive pump pressure.
• Controller: Standard Prelub “No Delay” logic delivers fastest possible start.
• Wiring Harness: Circuit breaker prevents harness and motor damage due to excessive current.
• Motor Switch: Rated for 200 A carry current yet consumes minimal power for activation.
• Installation Instructions: Application-specific instructions supplied for most machines.
• Inlet Hose: Rated for 121° C oil and will not collapse under pump vacuum.
• Pressure Hose: Rated for 121° C oil and burst at 3 times maximum pump output pressure.
• Check Valve: Prevents backflow of oil after engine start with minimal restriction and weight.

System Connections:
Plumbing
Custom fittings will be supplied that thread directly into the engine. The oil will be drawn through an oil pan port and returned to a port ahead of the existing engine filter.

• Oil pan suction fitting should have at least 0.28” (7mm) ID (#6 STOR, 6.35 mm NPT, M14) if used with viscous oil (15W-40 below 4.4° C). If a large port is not available, call for alternatives.
• Oil filter head return port should have at least 0.18” (4.5 mm) ID. (3.18 mm pipe, #4 STOR, M12)
• Install the pressure switch into the furthest downstream port in the engine’s pressurized oil system. Adapters are available to install the switch in most port types and sizes.

Electrical
Connect the motor to a source of power with the gauge of cables recommended on the next page. Install keyswitch and pressure switch adapter harnesses. Plug the main wiring harness into the connectors at the keyswitch harness, magswitch, pressure switch harness and control relay.
Motor-Pump Components and Features:

• Motor: Permanent Magnet DC motor. Insulated ground – More reliable than the case-grounded motor. High efficiency reduces current draw at all conditions and allows longer motor run time.
• Pump: Cast-iron housing with steel gears.
• Integral Relief Valve (175 psi) and seal-protection feature prevent motor or pump damage due to excessive pump pressure.
