VMQ1 Series Single and Thru Drive Vane Pumps

Vickers VMQ pumps provide continuous pressure ratings up to 293 bar (4250 psi) for the 25 frame size and displacements up to 488 cm3/r (29.78 in3/r) with the triple pump version. In addition, further reductions in noise levels of an intrinsically quiet design offer real possibilities in traditional internal gear pump applications.

The highly seizure-resistant surface of the bronze wafer plate is particularly forgiving in cold start-up applications.

Performance

• Vickers VMQ pumps meet global SAE and ISO standards
• Three single-pump and three thru-drive frame sizes are available in 20 displacements, ranging from 10 cm3/r (0.62 in3/r) to 240 cm3/r (14.65 in3/r)
• Continuous outlet pressure ratings reach 293 bar (4250 psi), with permissible peak pressures up to 310 bar (4500 psi)

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, ensuring exceptionally long shaft life.
• Unique bi-metallic wafer plate allows for cold start-ups.
• Efficient design means pumps perform under the harshest speed, temperature and cyclical loading conditions.
• Removable cartridges, usually with pump in-line, facilitate maintenance or flow changes.
• Increased power density
• Common inlet allowing for fewer ports and reducing the cost of redundant hose and fittings.
• Twenty-two displacements allow selection of the best flow output for optimum use of energy.
• Interchangeable cartridges between single, thru-drive, double and triple pumps, simplify cartridge selection and reduce inventory.
• High volumetric efficiencies, which increases productivity and reduces energy and operating costs.
• Compatible with a wide variety of fluids, including fire resistant and biodegradable fluids.
• Shaft seal options: single seal design for dry mount applications, or double seal design for fluid separation in wet mount applications such as gearboxes or where lubricant is always present. (Wet mount applications extend shaft life.)
