Description
Bijur Delimon - SureFire II Gear Pump Kit: 250cc Replacement Unit, Single Phase & 24VDC Compatible, Service Part
L. Dewitt's SKU #: 71128 | Mfr Part #: 71128The Bijur Delimon SureFire II Gear Pump Kit (71128) is the essential internal replacement pump for SureFire II automatic lubrication systems. This precision-engineered gear pump is responsible for drawing lubricant from the reservoir and generating the critical pressure required to actuate PDI (Positive Displacement Injector) or SLR (Single Line Resistance) distribution networks.
When to Replace This Part
If your lubrication system is failing to build pressure (preventing PDI firing) or showing decreased flow rates, the internal gear pump may be worn. Replacing the pump kit is a cost-effective alternative to replacing the entire motor-driven lubricator assembly, restoring your machine's protection against friction and wear.
System Performance
The [71128 Kit](https://www.bijurdelimon.com/default/71128.html) is rated for an output of **250cc/min**, ensuring that even complex networks with up to 100 lubrication points receive consistent, metered doses. It is designed for S1 Continuous Duty, making it suitable for 24/7 manufacturing environments.
