VMQ series vane pumps

Our Vickers® VMQ pumps are available in three single-pump and three through-drive frame sizes with displacements ranging from 10 cm3 to 215 cm3 [0.62 in3 to 13.12 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 can combine displacements from 110 cm3 to 488 cm3 [6.71 in3 to 29.78 in3]. Continuous outlet pressure ratings reach 293 bar [4,250 psi], and permissible peak pressures reach 310 bar [4,500 psi].The seizure-resistant surface of the bronze wafer plate is particularly valued for cold start-up applications.

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 

  • Dump truck  
  • Wheel loader  
  • Material handling
