Non-Return Valves WITT non-return valves protect plants, pipelines and outlet points against reverse gas flow and meet all relevant standards and regulations. The product range of non-return valves includes a large choice of nominal sizes (up to DN200) and flow rates (0.35 – 106 SCFH). The sophisticated valve technology of WITT non-return valves provides small pressure drops making them also suitable for applications with smallest opening pressures. A high-quality sealing system with elastomeres prevents leakages, and dirt filters at the inlet point assure long service life of the non-return valves. Some non-return valve models can also be used as flashback arrestors. All non-return valves can be mounted in any orientation, are available with all connections, in brass and stainless steel and are suitable for almost all technical gases.

The MBS hydraulic cylinders of the MZR-1002 series are direct support cylinders for vehicle construction. A robust cylinder connection is made possible by welding blocks. The support plates are ± 15 ° swivel. The cylinder connections have threaded holes for pipe connections according to BSPP ISO 1179-2. Hub and piston rod overhang are variably selectable. Control of the cylinders is possible on both sides via integrated hydraulically operated check valves in plate construction. With the exception of the piston rod, all surfaces are protected against corrosion with a black primer. On request alternative surface treatments are possible. The surface of the piston rod is hard chromed, ground and polished. The cylinders are suitable for hydraulic fluids of types H, HL and HLP according to DIN 51524/51525. If you have questions about areas of application or other options, we are happy to answer them. Download the data sheet for detailed information:

Trotec's most powerful submerged clear water pump TWP 9005 E pumps off up to 14,000 litres of clear to slightly contaminated water per hour. This makes it the perfect partner if you suddenly need to pump large amounts of water off or over quickly and efficiently. It is excellently suited for draining water from pools, for the quick elimination of leakages caused by a defective washing machine or of ground water ingress in basement rooms as well as of water that has penetrated the walls owing to a flood or heavy rainfall. Another possible application would be when work is required in drainage shafts. The maximum delivery head of the TWP 9005 E can amount up to 11.5 metres. An integrated check valve prevents the water from flowing back after switch-off and so reduces the time to restart suction. With its high-performance and maintenance-free 900 W motor the TWP 9005 E pumps off even slightly contaminated water with particle sizes of up to 5 millimetres.

Impressive 400 watts of power for pumping up to 7,000 litres per hourThe compact submerged clear water pump TWP 4005 E wows homeowners and passionate amateur gardeners alike with its high capacity and the user-friendly handling characteristics. The maximum feed rate of 7,000 litres per hour recommends the TWP 4005 E as much as the extraordinary pump height of 7.5 metres. An integrated check valve prevents the return flow upon switch-off. With its powerful and maintenance-free 400 W motor the submerged clear water pump TWP 4005 E conveys clear or only slightly contaminated water with particle sizes of up to 5 millimetres. The submerged pump drains flooded basements and laundry facilities at a remarkable speed. It can be used to empty swimming pools in a trice and further leaves a good impression when pumping over the water in cisterns and rain barrels that are full to the brim.

The CETATEST 715 series includes fully automatic working leak tester for the detection of untight parts within the cycle time of the production process. The leak tester uses a gauge pressure sensor and has a large measurement range. Therefore the CETATEST 715 is especially qualified for the simple testing of parts with large leakages, as they occur in the testing of valves. The test types "sealed component" and "dynamic pressure" can also be integrated. Typical applications: Testing of sanitary fittings, plastic welds, check valves Operating methods: Single-channel operation, two-channel operation The measurements in two-channel operation are synchronous. Measurement ranges: Max. +/-10,000 Pa Result units: Pa, hPa, PSI, Pa/s, hPa/s, mbar*l/s, ml/min, ml/h, l/min, l/h, mmHg, mmWs, Torr Pressure ranges: -1 bar, 200 mbar, 1 bar, 6 bar, 10 bar, 16 bar, 20 bar, negative gauge pressure and positive gauge pressure ranges can be combined.
