Hydraulics Online Component Expertise: Slack & Parr hydraulic flow dividers for mobile and industrial applications worldwide
Slack and Parr is a world leader in the manufacture of ultra-high precision gear metering flow dividers. Their unique approach, whereby all products are tailored to specific environment, application and specifications, means that customers benefit from the best 'whole of life product' return on investment.
Slack and Parr was founded in 1917, and by 1978 had established a hydraulic division – initially manufacturing hydraulic power packs, fuel pumps, flow meters and flow dividers. In recent years, the company took the strategic decision to specialise solely in the design and manufacture of high precision geared flow dividers, in rotation speeds ranging from 750 rpm to 3000 rpm.
Their expertise in high precision gear design technology now delivers world class performance for their customers; precision ground surface finishes on gear teeth and plate faces produce tight clearances and deliver a much higher accuracy and efficiency than any other comparable flow dividing technology available.
Suitable for a broad range of applications, Slack and Parr flow dividers are often deployed in lifting arms, and in pipe and drill clamping systems in: hydraulic presses, agricultural machinery, railroad track laying, waste compactors, lubrication systems, marine and sub-sea machinery, steel mills, specialist vehicles and transportation and in the oil and gas industry.

How to select the right hydraulic flow divider
The rotation speed depends on the capacity per revolution of the specific design, and the oil flow rate for each element in that design. While a hydraulic flow divider will generally work between 750 rpm to 3000 rpm, its optimum speed range is between 1000 rpm and 2000 rpm.
Flow divider elements each handle one division of the flow with the combination of elements being selected to achieve the desired oil flow within the speed range above.
This guide on selecting a hydraulic flow divider has been produced in conjunction with Slack and Parr. Their flow dividers are available with elements in several different sizes and in two distinct and discrete ranges:
- FDR range: 2 | 4 | 6 | 9 cc/rev capacity
- FDL range: 12 | 18 | 24 | 30 cc/rev capacity
