Pistons - Import export

Turned spindles, axles, shafts. Pistons for pneumatics, hydraulics, pumps. Ground, hardened, polished, chrome-plated.

The standard version is universally usable, but in special cases the light version can offer additional advantages.The light version is suitable for tight installation conditions and is also easier to fit in nonsplit grooves.This version reduces the friction. The low compression reserve with a negative effect on large tolerances must be considered.

By a highly intensive cooling, which is integrated in the crank casing a continous running at max 10 bar is ensured. In comparison with other compressed air compressors the big filter surface of the suction filter with 10 µ guarantees a long lifetime and an optimal suction behaviour. Due to the missing of external pipes the compressed air compressors of the range Marathon, are espescially compact. Advantages extreme long running life maintenance free low noise level continuous running

Plunger oil (lubricant) with ultrafine graphite for extremely good adhesion Type medium-viscous graphite oil Appearence black Application drip, spray suitable for "vacuum" die casting Properties and Advantages • well balanced tribological characteristics • despite 10 % graphite in medium-viscous oil product is sprayable and perfectly stable • high pressure resistance • highly efficient, economical in use • protection from erosion • dry-running operation feature • recommended for Caro-Prometa plunger systems

Rotating Piston Absorbers are displacement absorbers using hydraulic flow resistance. They are used to damp rotational vibrations, e.g. absorbers for ropeway cabins (see VDIRichtlinie VDI 3833 German Association of Engineers, sheet 1). The design is customized. Due to different operating conditions, no standard design is possible. (see also VDIGuideline, VDI 3833 sheet 1)

Ultra-compact and quiet pump series with low self-heating for run times up to 100% ED. The pump is self-priming up to approx. 6 meters.

These are the fastener rings made by brass.

When to use piston rings? When piston rings with excellent wear properties are required When simple assembly is of great importance When high edge loads occur When tailor-made solutions based on iglidur® materials are required When not to use piston rings? When the piston rings should seal simultaneously When different diameters should be covered by one part Before: with piston rings: Why complicate things when it can be done differently? Replace elaborately stamped PTFE tapes with a single clip-on guide ring, such as in lifting elements, control valves and fittings. We offer iglidur® piston rings made of freely selectable materials for a wide range of applications.

Due to the three-blade piston profile and the optimized housing shape, the 3RV Series fans are characterized by their high efficiency, low noise level and compact dimensions. The massive pistons cause a very quiet run of the blower.

These two-blade rotary blowers work on the Roots principle. They ensure the oil-free transport of air and almost all technical gases.

Based on our large product portfolio, we are the right contact for your new projects. Please send us your inquiries.

Most spare parts can be delivered from our well stocked warehouse. If these are parts of older machines that are not available from stock, we will manufacture them ourselves in our machinery. Wear parts such as oil, filters and V-belts can also be supplied at any time.

With us, your rotary blowers are in the best hands. This applies to regular Maintenance work such as oil or filter changes, up to complete overhauls of your units, at our factory or at your site. Of course, we also carry out this work on rotary lobe blowers of other makes.

Our product range comprises thirteen series for maximum pressure ranges from - 450 mbar to + 1000 mbar and flow rates from 0.41 m³ / min to 260 m³ / min. The series differ in different lengths, by the piston profile (2 or 3-leaf), the conveying direction (horizontal or vertical) and the housing seal. This means that the right device can be designed for every application.
