Maintenance Procedure

Safety Check & Preparation

Ensure the unit is powered off and isolated. Verify zero pressure in the inlet/outlet lines. Clean the exterior of the pump to prevent debris from entering the housing during disassembly.

5 min Mandatory

Remove Housing Bolts

Locate the four (4) M8 hex bolts securing the front casing to the motor housing. Using a 13mm socket wrench, loosen and remove the bolts in a cross pattern to prevent warping the casing.

13mm Socket HB-500..503

Detach Front Casing

Gently tap the side of the front casing with a soft mallet to break the seal. Carefully pull the casing straight out to avoid damaging the internal components. Set the casing aside on a clean cloth.

Inspect Impeller

Visually inspect the brass impeller for signs of cavitation, erosion, or bent blades. Rotate the shaft by hand to ensure it turns freely without grinding. If the impeller is damaged, it must be replaced.

Check Wear IM-303

Check & Replace Seals

Remove the old O-ring seal from the groove. Clean the groove thoroughly. Inspect the new O-ring for defects. Lightly lubricate the new O-ring with silicone grease and install it into the groove.

Silicone Grease OR-404

Reassembly

Align the front casing with the motor housing. Insert the four hex bolts and hand-tighten. Torque the bolts to 25 Nm in a cross pattern. Reconnect power and test for leaks.

Torque: 25 Nm

Troubleshooting

Symptom	Possible Cause	Action
No Flow	Clogged impeller or air lock	Disassemble and clean / Bleed air
Loud Noise	Worn bearings or debris	Inspect impeller and bearings
Leaking	Damaged O-ring seal	Replace seal (See Step 05)
