Frequently Asked Questions
The most efficient way to get started is to give us a call. With over 100 years of combined experience, our expert team of technicians, industry specialists, and metallurgical engineers are here to guide your decision.
Every piece of equipment varies to some degree but you can't go wrong with regular fluid changes, seal replacements, and belt maintenance. We can help you figure out whats best for your equipment.
We offer bolt-on upgrades for many Stokes models, including in-line filtration, fail-safe lubrication systems, high-efficiency Baldor motors, and clapper-to-poppet valve conversions for Stokes 412H and 412J models. For Stokes 306 and 310, as well as Roots 607 and 615 blowers, we provide mechanical seal conversions. We also offer 15-degree low-helix gear sets for Stokes 607, 615, and 622 blowers—dramatically reducing axial bearing load and enhancing performance.
Yes, all pumps sold or remanufactured by MHV come with our one-year warranty, or 18 months after delivery if the equipment isn’t installed right away—and it’s a warranty we stand behind.
