FAQs
Q1: What is the minimum order quantity (MOQ)?
A1: Standard MOQ is 10 units. Custom branding or connection standards may require a higher MOQ depending on scope.
Q2: What water quality is suitable?
A2: Designed for clean to slightly turbid water without large solids. For abrasive/slurry media, consult for specialized impellers and wear parts.
Q3: How does self-priming work?
A3: The pump self-primes when the casing is initially wetted; using a foot valve helps retain prime between uses. The typical priming rate is ~70 s per meter of suction lift.
Q4: What are the maintenance requirements?
A4: Follow the service schedule; check/replace engine oil regularly (0.75 L, SAE 10W-30/15W-40, ≥CD grade) and keep air filter and strainers clean.
Q5: Which model should I choose—B or BE?
A5: YDP50B is manual recoil start for simplicity; YDP50BE adds electric start for convenience and rapid turn-ups.
