Hydraulic specialists for sales and repairs. Products supplied are pumps, motors, valves, filters, seal kits etc. Distributor for Danfoss, Turolla, Parker Hannifin and Hy-Pro.
A customer needed a Hy-Pro V5 spool valve with a rotary lever and as it is for a maritime application it has been assembled using a marinised worksection (corrosion resistant).
The Hy-Pro V5 rotary lever has been developed to enable the operator precise control of motors and cylinders. The lever swings through an 130° arc and works by means of a scroll which converts the rotary action of the lever into axial movement of the spool. The centring mechanism has a friction detent feature which positively holds the spool in neutral then maintains the selected position.
Application
Used extensively in the forestry and fishing industry to control the speed of conveyors and winches.

P & R Hydraulics is an official distributor for Hy-Pro
(Hydraulic Projects Ltd) and can supply assembled units or individual
components. Please contact our sales team on tel: 01603 424880 for more
information.
P & R Hydraulics is a sales distributor for Turolla (a member of the Danfoss Group), which means we buy direct from them
and can supply the items to you at very competitive prices. We hold a
wide range of Turolla products in stock because we understand the need
to keep your equipment running for maximum productivity. One such
product is the Group 3 series of aluminium gear pumps, of which we have a variety of models
on our shelves.
The Turolla Group 3 series is a range of peak performance fixed-displacement gear pumps. Constructed of a high strength extruded aluminium body with aluminium cover and flange. All pumps are pressure balanced for exceptional efficiency.
Features and benefits of Group 3 gear pumps
• Wide range of displacements from 22 to 90 cm3/rev [from 1.34 to 5.49 in3/rev]
• Continuous pressure rating up to 250 bar [3625 psi]
• Speeds up to 3000 min-1 (rpm)
• SAE, DIN and European standard mounting flanges
• High quality case hardened steel gears
• Multiple pump configurations in combination with SNP1NN, SNP2NN and SNP3NN
Pump design
SEP3NN
The SEP3NN gear pump is available in a limited displacement range from 22.0 to 44.1 cm3/rev (from 1.34 to 2.69 in3/rev). They are suitable for applications where the pressure is lower than 210 bar (3045 psi). The SEP3NN range is released into SAE and European configurations. The overall length is reduced by 12mm (0.47 in) in respect of the SNP3NN.
SNP3NN
The SNP3NN is available in the full displacement range from 22.0 to 88.2 cm3/rev (from 1.34 to 5.38 in3/rev), and with higher pressure ratings than the SEP3NN. This is due to the pressure balance on each side of the gears obtained with pressure-balance plates made in antifriction alloy that contribute to high volumetric efficiency and maximum sealing as well.
For more information on these pumps (and spare parts) please contact us - tel: 01603 424880.
Parker’s broad range of energy-efficient hydraulic pumps includes
displacement models of variable piston, fixed vane and fixed gear pumps.
Designed to handle a wide range of applications, Parker pumps are
available with electronic and computer controls and, like all Parker
products, these pumps are manufactured with the finest materials under
strict quality control.
Being an authorised Parker Hannifin distributor, as well as all the
pumps listed below, P & R hydraulics can obtain other units, spare
parts and accessories for any Parker hydraulic pump. Additionally, we
can inspect, repair and test Parker units; modify existing units and
custom build units according to your specification and the application
to which it is being turned.
Gear Pumps – fixed displacement, cast iron body
These are three-piece cast iron construction and suitable for heavy
duty application. They have a long life, even in severe environments;
can be assembled as single, multiple or piggyback configurations, as
well as either a pump or motor.
