Every Oil Pump Tested at Operating Speed: Stable Oil Output, Fewer Bar Complaints
Flow bench testing on in-house commercial oil pumps
A chainsaw is only as reliable as its lubrication. When the guide bar runs dry, the chain overheats, cutting slows, wear accelerates, and the end user blames the saw — and the brand behind it.
At Yueqing Zhongfan International, we test every oil pump we produce on a test bench at operating speed. Each pump is run and checked to verify that its oil output per minute is stable and meets the required standard. This is a 100% inspection, not a sample check: every unit is tested before it leaves our factory.
Why does that matter for distributors and brand owners?
- Fewer oil-starvation complaints. A pump that delivers stable oil flow keeps the guide bar lubricated in real working conditions, helping to eliminate the dry-bar complaints that damage a brand's reputation in the field.
- More consistent performance from unit to unit. Testing at operating speed, rather than at rest, shows how the pump actually performs when it matters — under load, at the speed it will run in the saw.
- Less risk for your brand. When a replacement part fails, the customer rarely blames the part alone. Full inspection is our way of protecting the reputation you have built with your customers.
We supply aftermarket chainsaw and brushcutter spare parts, including oil pumps, sprockets, clutch drums, rims, clutches and chain adjusters, to distributors and brand owners worldwide. If you are looking for an oil pump supplier who tests every unit at operating speed, we would be glad to support you.
