Components

Beside our testing machines, we also offer single components, which are essential to operate our testing machines.

Testing Cylinders

Testing cylinders can be delivered in two different pressure stages (210/280 bar).

Hydro-static Testing Cylinders

Application

Testing cylinders mounted in hydro-static way serve to generate static and dynamic test forces for frequencies up to 100 Hz.

Features

Standard series includes force range from 6 to 2000 kN

Testing cylinders are provided with:

  • Double working cylinder with the same piston surface area and piston rods on both sides
  • Hydrostatic bearing to absorb transverse forces with special metallic slide coating
  • Leakage-free sealing of the piston rod
  • Inductive and incremental displacement transducer
  • Connection block for the attachment of various servo-valves with different  dynamic and flow rates
  • Pressure reservoirs and flushing plate

Differential Testing Cylinders

Application

Differential testing cylinders are used for static and quasi-static tests of up to 15 Hz, especially for compression tests.

Features

  • Compact design
  • compression side with higher forces than tensile side

Synchronized Testing Cylinders

Application

Synchronized testing cylinders are suited for static and quasi-static tests of up to 15 Hz.

Features

  • Tensile side and compression side with same test forces

Servo-pneumatic Diaphragm Cylinders

Application

Diaphragm cylinders are suited for load frequencies of up to 50 Hz. WPM offers the series 2, 5, 10 und 25 kN an.

Features

  • Work friction-free
  • Stroke ± 2.5 oder 5 mm
  • Height 52 oder 95 mm
  • Diameter 200, 294 oder 380 mm

Load Producer "Pneumatic Muscles"

Application

„Pneumatic Muscles“ are used for nonstandard load cases to apply static preloads for test forces up to 6 kN.

Features

1 to 6 pieces can be combined

Aerostatic Mounted Pneumatic Testing Cylinders

Application

Aerostatic mounted pneumatic testing cylinders can be applied for a wide range of load frequencies. They are used for test forces of 2 or 5 kN with 6 bar.

Features

  • Work with „air-cushioned“ bearings
  • Stroke ± 20 or 150 mm
  • diameter 160 mm
