PRONAL EXP and STP hydraulic compensators and transformer bladders

Elastomer compensators from PRONAL feature STP transformer rubber bags and MTP membranes protecting dielectric oil against oxidation. The BRR relay sensor detects bladder rupture inside conservators. Hydraulic separators EXP (1 to 70 L) and MAB surge membranes absorb pressure spikes.

Aramid-reinforced construction of CLT lifting bags and CPF stack cushions

High-pressure pneumatic lifting cushions in the PRONAL CLT series are manufactured via hot autoclave vulcanisation of synthetic elastomers reinforced with multi-layer aramid cord fabric.

Featuring a slim insertion profile for tight clearances, CLT cushions deliver lifting forces up to 65 tons at a maximum working air pressure of 8 bar.

Interlocking CPF stack bags operate at pressures up to 10 bar with capacities reaching 81 tons while maintaining a flat contact footprint throughout the vertical stroke.

Lower-pressure operations utilize cylindrical CLC cushions (1 bar, 12 tons), CBP bags (0.5 bar, 5 tons), and PARC aircraft recovery bags.

Engineering application of VTR inflatable jacks and elastomeric expansion seals

Flat elastomeric inflatable jacks from PRONAL in square, circular, and rectangular geometries replace hydraulic cylinders in confined machinery spaces at working pressures up to 7 bar, with custom-engineered versions exceeding 10 bar.

The VTR inflatable jack series (operating between 2.5 and 5 bar) is purpose-built for uniform axial clamping and lifting of power transformer windings without damaging delicate paper-oil insulation.

Annular and profile inflatable seals rated up to 7 bar fit directly into autoclave doors, process hatches, and sluice gates, expanding upon inflation to form a leak-tight barrier and retracting immediately when vented.

Backpressure rating and deployment of OPL, OPAP, and OFR inflatable pipe plugs

Standard inflatable pipe plugs in the PRONAL OPL series seal internal pipeline diameters ranging from 29 to 760 mm during maintenance and hydrostatic testing; bypass-equipped models allow continuous media diversion or test water injection.

High-pressure reinforced pipeline stoppers withstand backpressures up to 35 bar and higher in oil, gas, and subsea conduits.

Emergency anti-pollution stoppers in the OPAP series (for pipe diameters under 1000 mm) and OFR series (for collector diameters from 800 to 2100 mm) install permanently inside industrial drainage networks to isolate chemical spills and contaminated firewater runoff.

Field deployment of flexible storage tanks and RAM bolted fuel bladders with ATEX pumps

Pillow-style flexible storage tanks from PRONAL are fabricated from high-tenacity technical fabrics coated with specialized elastomers or plastomers matched to the stored liquid: potable drinking water, liquid nitrogen fertilizers, industrial effluents, or aviation and diesel fuels.

Firefighting water reserve bladders are produced in standard capacities from 60 to 360 m3. For bulk field fuel depots, bolted RAM storage tanks hold up to 500 m3 of hydrocarbons.

Complete storage systems are supplied with isolation manifolds, breather vents, and standard or ATEX-rated diesel and electric motor-driven transfer pumps.

Transformer dielectric oil preservation with STP bladders and EXP hydraulic compensators

Installed inside power transformer conservator tanks, soft elastomeric PRONAL STP rubber bags and MTP flexible diaphragms isolate dielectric insulating oil from atmospheric oxygen and moisture across thermal expansion cycles.

Continuous membrane supervision is provided by the BRR bladder rupture relay sensor, which triggers an immediate alarm if oil enters the air chamber.

Within closed hydraulic circuits on cranes, presses, and mining machinery, EXP hydraulic oil separators (standard volumes from 1 to 70 L) and MAB surge vessel membranes accommodate fluid volume variations and dampen water-hammer pressure spikes.

Automated bottle palletizing with MCS, MCB, and MC/ML pneumatic grippers

Across high-speed beverage bottling and packaging plants, PRONAL MCS pneumatic tube grippers and MCB double bottle grippers enable simultaneous full-layer handling of glass and PET containers.

Long-neck MC/ML and short-neck MCC tube grippers operate at compressed air pressures up to 1.2 bar, gripping bottle necks gently without mechanical shock or glass breakage.

Specialized MDG half-grippers for thick-neck decanters and MCP moulded elastomer grippers adapt to custom flask geometries, mounting directly onto robotic palletizing and depalletizing heads.
