PT wellpoint pump runs 69000 operating hours until the first engine change

15 October 2018

That’s a first for us too! After 69000 operating hours, it was deemed time to replace the diesel engine on a PT series pump at Geverinck, a Dutch wellpoint dewatering company. "It was still working, but we did not want to risk it further for longer lasting projects".

It has been twenty years since BBA Pumps selected Hatz as its engine supplier for the PT wellpoint dewatering pumps. The philosophy - pump and motor perfectly balanced - was always central to the design of new diesel pump sets. This concept has proven to deliver the best results for the user. We are proud to learn from satisfied customers that they achieve 30,000 to 35,000 running hours with their first diesel engine.

But how could Geverinck put almost double on the clock?

Clemens Geverinck, the owner of the dewatering and pump rental company, confirms that this was no real surprise to them. "We already had a few PT pumps with a lot of operating hours on the Hatz. We just change the oil and filters in time, make sure that the valve clearance is good and occasionally fit a new injector. In addition, we always keep the engine speed at the factory setting, and that’s all there is to it." Clemens says.

What this incredible number means

  • Perhaps 69000 operating hours does not immediately mean much, but driving a car at an average speed of 70 km/hour would mean travelling almost 5 million kilometers.

  • At an engine speed of 1500 rpm, the engine crankshaft has turned more than 6 billion times without the bearings being replaced.

  • The PT pump from Geverinck was produced in 2004 and has therefore averaged 5000 hours per year on wellpoint dewatering projects.

  • Unlike the current DriveOn® pump sets, the service interval with this Hatz 1D81Z was every 500 hours. This engine has had more than 130 maintenance intervals.

  • We have not yet talked about the PT pump itself, which is still going to have a few more engine changes yet before its ready to retire...
