Reader offers a wide range of high-performance pumps, which provide grout outputs of up to 200 litres (45 gallons) per minute and grout pressures of up to 1500 psi (100 barƹ and will, therefore, meet the most demanding operational requirements across a wide range of applications.

The D2/8, D3/8 and D4/8 models are all double cylinder air-operated piston pumps which are powered by heavy duty double-ended pneumatic cylinders, which, in conjunction with ball-type non-return valves, produce a continuous output of grout.

The S3/8 is a single cylinder air-operated pump, powered by a heavy duty single pneumatic cylinder. Owing to its comparatively small size and compact desgin the S3/8 is ideal for use in areas of confined working space, such as tunnelling and sewer refurbishment.
