VMQ series vane pumps
Vickers® VMQ pumps are available in three single-pump and three through-drive frame sizes and 20 displacements ranging from 10 cm3 to 240 cm3 [0.62 in3 to 14.65 in3]. Four double-pump configurations offer combined displacements from 20 cm3 to 398 cm3 [1.23 in3 to 24.29 in3], and two triple-pump configurations offer combined displacements from 110 cm3 to 488 cm3 [6.71 in3 to 29.78 in3]. Continuous outlet pressures up to 293 bar [4,250 psi] and peak pressuress up to 310 bar [4,500 psi] are accommodated, and the seizure-resistant surface of the bronze wafer plate is particularly useful in applications requiring cold start-ups.
Features and benefits
- Hydraulically balanced design (no internal radial forces) gives almost limitless shaft and bearing life.
- Extremely low noise levels enhance operator comfort.
- Shafts easily handle maximum pressures, providing exceptionally long shaft life.
- Unique bi-metallic wafer plate allows for cold start-ups.
- Efficient design with common inlet allows for fewer ports.
- Removable, interchangeable cartridges, usually with pump in-line, facilitate maintenance or flow changes.
- Compatible with a wide variety of fluids, including fire resistant and biodegradable fluids.
Applications
- Oil and gas
- Metal cutting
- Plastic injection molding
