Hydra-Cell™ high pressure coolant pumps are sealless, meaning they do not have cups, packing or mechanical seals (the primary source of wear and maintenance for high pressure centrifugal and piston pumps). The inherent reliability of the Hydra-Cell™ design ensures minimal maintenance and down time when pumping reclaimed machine tool coolant. The only maintenance required are periodic oil changes and replacement check valves approximate every 4,000 hours (6 months) of operation.
Conventional coolant pumps require fine filtration, in some instances as low as 25 microns. Filtering coolants to that degree can remove the very additives that enhance their performance. Over-filtering your coolant also results in high filtration costs (media cost, storage, labor and disposal).
Hydra-Cell™ high pressure coolant pumps are generally protected with a 40 mesh (400 micron) screen or filter bag, so your filtration is not dictated by our pump but by whatever your rotary union or other system components require.
We provide complete pump/motor skid's based upon the flow rate and pressure required for your machining center. To properly size a high pressure coolant pump system we need to know the flow rate and pressure you require. Your tooling supplier can look-up your largest tool and advised the coolant flow rate required for your desired pressure - and that's all we need to generate an itemized proposal!
We designed a separate website for high pressure machine tool coolant pump applications at https://cnc-coolant-pumps.com/; at this site you will find detailed descriptions of each pump system size along with accessories such as portable sump cleaning systems to help reclaim and extend your coolant's useful life as much as possible.
