The David Brown Hydraulics pump range includes helical gear and spur gear pumps together with cast iron and aluminium bodies. High durability, long life, and high efficiency are features of these pumps, which, when combined with the low noise characteristics of the helical gear pumps, make them highly suitable for modern machinery.
Depending on model, features include: spur gears, helical gears, displacements from 16 to 239cc/rev, uni-directional or reversible motors, single or multiple assemblies, cast iron or aluminium bodies, high pressure ratings
Q Series Overview
Overview brochure with all the technical details relating to the entire Q Series product range.
For data on each individual frame size see the individual product brochures below.
Q Series QR4/QS4 spur and helical gear range
This range of pumps, available in an extensive range of options, comprises a modern, quiet, spur gear model (R4) available in 9 displacements from 16 to 60 cc/rev, and the modern, super quiet helical model (S4) available in 6 displacements from 16 to 40.6 cc/rev. The helical models generate lower noise levels than conventional, so called, quiet pumps and have the added benefit of higher efficiency.
Q Series QR5/QS5 spur and helical gear range
This range of pumps, available in an extensive range of options, comprises a modern, quiet, spur gear model (R5) available in 7 displacements from 45 to 120 cc/rev, and the modern, super quiet helical model (S5) available in 5 displacements from 43.5 to 82.2 cc/rev. The helical models generate lower noise levels than conventional, so called, quiet pumps and have the added benefit of higher efficiency.
Q Series QR6/QS6 spur and helical gear range
This range of pumps, available in an extensive range of options, comprises a modern, quiet, spur gear model (R6) available in 6 displacements from 100 to 220 cc/rev, and the modern, super quiet helical model (S6) available in 5 displacements from 80.3 to 149.9 cc/rev. The helical models generate lower noise levels than conventional, so called, quiet pumps and have the added benefit of higher efficiency.
Q Series QS7 helical gear range
This range of pumps, available in an extensive range of options, comprises a modern, super quiet helical model (S7) available in 4 displacements from 149.9 to 239.8 cc/rev. The helical models generate lower noise levels than conventional, so called, quiet pumps and have the added benefit of higher efficiency.
