- Flow: how much water or slurry you need to move, in litres per minute. Work it out from the volume to drain and the time available.
- Total head: add the suction height (from the water to the pump), the discharge height (from the pump to the outlet) and the hose losses, which grow with length and bends.
- What you will pump: for slurry or sandy water choose a solids-handling pump with an abrasion-resistant impeller.
- Suction and discharge diameter: it must match your hoses; a narrower hose reduces flow.
- Altitude: diesel engines lose power at higher altitude. For high-mountain work ask about a turbocharged engine.
- With that data (flow, head and type of fluid) message us and we will recommend the right unit.
Basic diesel engine maintenance
- Before starting: check oil and coolant levels and look for leaks.
- Air filter: mining sites are dusty; check and clean it often. A clogged filter cuts power and wears the engine.
- Clean fuel: drain water from the fuel separator filter and store diesel in clean, closed containers.
- Radiator: keep the fins clean and check the hoses and the fan belt.
- Oil and filter changes: follow the hour-meter intervals in the manual, not just the calendar.
- If you notice abnormal smoke, loss of power, knocking or overheating, stop the unit and contact us.
How to order the right spare part
- Take a photo of the engine or unit plate: it shows the model and serial number.
- Photograph the damaged part from several angles, with a ruler or tape next to it to show the size.
- If you can, note key measurements: diameter, number of teeth, thread type or length.
- Search the spare parts catalogue filtered by your engine, or send everything on WhatsApp and we will confirm the part.
