GV pumps can offer real cost of ownership savings. The GV pumps are robust and reliable, delivering a reduction in process downtime which would lead to lost production. In addition, the minimized cost of routine maintenance (such as oil and filter replacement, spares inventory holding and oil disposal) all adds to the savings using GV dry pumps. With service intervals of 18 months for re-greased bearings and 3 years for bearing changes, the GV pumps offer a highly reliable and cost effective alternative to piston pumps.
