Bladder pressure tank, Hectron (industrial filtration)

Bladder pressure tank — Hectron (industrial filtration) — industrial filtration solution distributed by DIMM.

Why filter in industry

In industry, agriculture, irrigation and process-water treatment, reliable filtration protects pumps, heat exchangers, nozzles, membranes and instruments against suspended particles. Sand, silt, oxides and organic matter cause wear, clogging and efficiency loss; controlling them at the source extends equipment life and secures production. The right device depends on flow rate, required fineness and raw-water quality.

Principle

This bladder tank stores water under pressure and absorbs network variations, protecting pumps against frequent starts and water hammer. The bladder separates water from air, preserving water quality and installation life.

How it works

Volume (e.g. 60 L) and nominal pressure (PN) are chosen by flow, pressure range and admissible pump starts. Versions with interchangeable bladder (MAXIVAREM type) or stainless body for demanding water.

Applications

Applications: Surpression, Protection de pompe, Réseaux d'eau, Forage.

Specifications

Key strengths

• Stabilises network pressure
• Protects the pump (fewer starts)
• Dampens water hammer
• Interchangeable bladder or stainless body
• Several volumes and PN

Materials & durability

Material choice directly determines service life in demanding environments. AISI 304 stainless suits tap water, while AISI 316L withstands chlorinated, brackish and process water; PVC-U offers remarkable chemical inertia against acids and bases. Body, wetted fasteners and seals (EPDM or nitrile) are selected to avoid galvanic corrosion and ensure years of reliable operation, even in continuous duty.

Performance & operation

Operationally, the goal is to filter effectively while controlling costs. Automatic filters clean their screen with very low water use and no production stop; bag and cartridge filters offer a large filtering surface and low pressure drop, spacing out interventions. When correctly sized, a device reduces wear on downstream pumps and membranes and improves the installation's overall efficiency.

Integration & supervision

Integration is eased by standardised connections (threaded or flanged DN) that allow fast mounting or replacement on existing networks. Automatic filters feature an electronic box with indicators and a cycle counter, plus connectable feedback to a supervision system; protection ratings (up to IP65) and high-temperature or high-pressure versions cover harsh industrial environments. Each option is ordered separately to match the device to its context.

Correct sizing

Three parameters drive the choice: flow rate (m³/h), filtration fineness (microns) and water quality. Material is selected by corrosivity: AISI 304 stainless for tap water, 316L for chlorinated, brackish or process water, Marine or PVC-U versions for very aggressive media. Service pressure and maximum temperature also determine the range and options. DIMM helps size the installation to these constraints.

Range & compatibility

This reference is part of the Hectron industrial-filtration offer from DIMM: automatic self-cleaning filters, stainless or PVC-U housings and multi-filters, bag filters, hydrocyclones, pressure-sustaining valves and accessories combine into a complete line, from coarse to fine filtration, matched to each process.

Installation & maintenance

Installation is in-line, respecting flow direction, with upstream/downstream isolation valves for easy maintenance. On automatic filters the wash cycle is driven by a pressure switch and cycle counter; on cartridge or bag filters the media is replaced as pressure drop rises. Regular maintenance ensures stable flow and durably protects downstream equipment.
