Performance: The D17 model delivers high-volume flow up to 15.5 GPM (58.7 l/min) with extreme pressure capabilities reaching 2500 PSI (172 bar).
Designed for large-scale CNC operations, the D17 is a vertical, sealless diaphragm pump that excels in high-pressure chip management. Its vertical orientation is ideal for integrated tank systems where floor space is at a premium.
The D17 series handles abrasive "fines" without the wear associated with traditional plunger pumps. By eliminating mechanical seals and packing, the D17 ensures leak-free operation even in the harshest 24/7 machining environments.
Although capable of 15 GPM with an 1800 RPM motor, the most common configuration uses a 1200 RPM motor for a flow rate of 10 GPM at pressures from 1000 to 2500 PSI. The pressure regulating valve ensures that the pressure at the tool does not exceed the maximum desired pressure by bypassing any excess coolant back to the reservoir, thus there is no need to control the motor speed.
A significant feature of D17 Hydra-Cell high pressure coolant pumps are their ability to reliably pump reclaimed coolant. Whereas piston, plunger and multistage centrifugal pumps require fine filtration of your coolant, perhaps as fine as 25 microns, the D17 coolant pump only requires a 20 mesh screen (equivalent to a 800 micron filter bag). Therefore other system components, such as your rotary union or tool, dictate the required filtration level. In some cases we can replace your bag filter housing filter bag support basket with a mesh lined version to eliminate filter bag usage altogether!
Maximize manufacturing time with D17 Hydra-cell high pressure coolant pumps as they only require an oil change every 2000 to 4000 hours of operation and check valve replacement every 6000 to 9000+ hours of use. D17 coolant pumps use 2 quarts of standard 10W30 synthetic motor oil and changing the oil is as simple as draining the old oil and pouring in the new oil. Check valve kits cost <$800 and can be installed in under 2 hours; there are no special tools or training required to replace worn check valves. When check valves wear it is noticed by a rougher running pump and inability to maintain a consistent pressure. Unlike other pumps having cups, packing and mechanical seals which leak, there are no fugitive emissions concerns with D17 high pressure coolant pumps.
