Questions

FAQ

What outlet sizes are available for QJMC self‑priming water pumps? What are their flow rate and head parameters?
Our main‑selling models are 2‑inch and 3‑inch gasoline‑powered self‑priming water pumps with in‑house die‑cast aluminum pump housings. Exact flow rate, head and suction‑lift figures vary by model. Please check product pages or contact sales for the full specification sheet.
How do I choose between rated power and peak power for generators? What is the function of AVR?
Rated power refers to sustainable continuous output, while peak power is the instantaneous maximum output at startup. We recommend reserving a 20 % power margin against your total load. AVR (Automatic Voltage Regulator) stabilizes output voltage and protects sensitive electric devices such as computers and lamps.
Are pump parts interchangeable? Can I purchase wearing parts separately?
QJMC original spare parts fit the corresponding pump models. Wearing components including seals, impellers, spark plugs and recoil starters can be purchased individually. Long‑term spare‑parts supply is guaranteed.
What terrain and operations are suitable for the power tiller? What cutting tools are available?
It works on mountain land, hilly ground, orchards, greenhouses and other small‑size farm plots for tasks such as rotary tilling, weeding, ditching and ridging. Rotary tiller blades come as standard; optional accessories include weeding wheels and ditchers.
What is the typical lead time for delivery?
Standard export cartons or wooden cases with shock‑absorbing foam inside, suitable for long‑distance sea and land transport. Custom shipping marks are available upon request.
What preparations are required before pump startup? Why is priming water needed?
Fill the pump chamber fully with priming water to expel internal air; otherwise the pump cannot build vacuum for suction. Also inspect suction‑pipe joints for tightness and clean clogged strainers. Never run the pump dry without water.
What causes low or no water output from the pump?
Common causes:
① Insufficient priming or air leakage on suction piping;
② Blocked suction strainer;
③ Actual suction lift exceeds rated maximum;
④ Impeller tangled with debris;
⑤ Insufficient rotating speed.
Troubleshoot following this sequence.
What to do if the generator fails to start or stalls after startup?
Check these items in priority:
① Fuel valve open and adequate gasoline supply;
② Proper oil level (low‑oil protection will trigger automatic shutdown);
③ Carbon‑fouled spark plug;
④ Correct choke position.
How to maintain the equipment and what are storage requirements?
Clean air filters and check oil level after every use. Change engine oil and service spark plugs periodically. For long‑term storage, drain all fuel and oil completely. Store in dry, well‑ventilated space away from sunlight and rain.
Is there a product warranty? How is after‑sales service handled?
One‑year warranty against non‑human‑caused damage (wearing parts excluded). Overseas buyers obtain local dealer after‑sales support, or may contact us directly for technical guidance and spare‑part supply.
