Magnum MTP4000S — Pump Set Up
Installation
For the Magnum MTP4000S, from the Magnum operator's manual.
Applies to: John Deere PE4024TF281 engine
Before you start
- If a manual shutoff valve is installed in the discharge line, it must not be left closed during operation
- The pump will not prime when dry; extended operation of a dry pump will destroy the seal assembly
- Never open the priming cover on a pump that is hot or that has been operated recently
Procedure
- Disconnect the pump from the tow vehicle, chock the wheels to prevent rolling.
- Lower the rear leveling jacks and adjust until the pump is as level as possible.
- Attach fittings to intake and outlet openings; ensure gasket/seal is in place and tighten all hardware.
- Attach a rigid hose to the intake (suction) side; suction hose/piping should be at least as large as the pump flange.
- Attach a rigid intake screen or strainer to the end of the suction hose.
- Place the intake hose into the liquid; submergence should be four to five times the pipe diameter.
- Attach a flexible hose to the outlet (discharge) side; use a concentric taper to increase discharge diameters.
- Check intake and outlet hoses for sharp bends or kinks; intake hose should slope upwards toward the pump.
- Fill the pump casing half full with liquid to prime; replace cover and tighten clamp screws hand tight.
Specs & values
- Intake screen openings must equal four times the area of the intake hose
- Suction hose submergence 4-5 times the pipe diameter
