Frequently Asked Questions — Water Pumps
Sizing, connections, head and flow, and where to get spares.
How do I size a water pump correctly?
Three measurements decide the pump:
- A · Suction depth — from pump centre down to the water. Beyond 6-7 m a surface pump fails; use a submersible.
- B · Delivery height — vertical rise to the top of the tank. 10 m = 1 bar of pressure.
- C · Pipe distance — the real length of pipe from pump to tank. Count every 10 m of horizontal run as 1 m of head.
Surface, submersible or booster — which is mine?
Surface pumps sit above the water (suction lift up to ~7 m). Submersibles go inside the well or borehole for deep water. Boosters raise pressure in an already-piped system.
Petrol, diesel, electric or solar?
Petrol and diesel suit farms and sites without grid power. Electric is quiet and cheapest to run where power is reliable. Solar pumps run directly from panels with no fuel cost.
Why is my pump losing pressure?
Common causes: air in the suction line, worn impeller or seal, blocked foot valve, leak on the suction side, or wrong rotation on a three-phase pump. Let it run with the outlet open to purge air first.
