Axial Piston Motors – fixed displacement, bent axis

The F1 is a fixed displacement bent axis, truck hydraulic motor that can tolerate low temperature and high temperature shocks, and high acceleration.

F11/12 is the high performance bent axis, fixed displacement heavy-duty motor series.  They can be used in numerous applications in both open and closed loop circuits.  The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor.  The simple straightforward design with very few moving parts, make them very reliable motors.

Coloured cable ties

Ingenious use for coloured cable ties!

A 10 bank spool valve was brought into our workshop for inspection. Prior to removing the valve coloured cable ties were fitted to all inlets and outlets of the valve and machinery. The colour cable ties will greatly assist with the refitting of the valve.

The Italian Job

Turolla Distributor (UK)It’s not JUST who you know, it’s how WELL you know them that really counts.

P & R Hydraulics were invited to attend the formal opening of the new Turolla manufacturing plant at Bologna, Italy, last month. We were guests of Trevor Pritchard, Sales Development Manager, because we have a very close working relationship with Turolla, have demonstrable expert knowledge of Turolla hydraulic products, plus additional specialist knowledge of hydraulic systems.

So, of course we were pleased to be invited, but was it just an excuse to go mad on delicious pizza and pasta? Absolutely not!

We were fascinated to watch an extremely detailed demonstration of their new ‘Sshark’ hydraulic pump range. Why the “Shhhh…”? Because the ‘Sshark’ is the first of a new generation of hydraulic pumps developed by Turolla with much reduced noise output, over 15dB in the case of their flagship product, the ‘Shhark Continuum’, making it perfect for any application where particular attention to the local environment is required.

More details can be found here Shhark brochure, and of course we will present more details as soon as they are available to non-OEM customers.

For more information on Turolla products please contact us - tel +44 (0) 1603 424880.

Hy-Pro V5 spool valve with rotary lever

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.

Features

  • 130° movement
  • Compact design
  • Spool options
  • Detent in neutral
  • Friction hold
  • Robust mechanism
  • Toughened components
  • Cast iron body and scroll

Turolla Aluminium Gear Pump - Group 3

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.
