Jessberger JP-810.160 Air-Operated Diaphragm Pump 1" 170 l/min — ATEX Zone 2 | ALU

The JP-810.160 is the aluminium variant of the JP-810.170 platform — a 1" AODD pump delivering 170 l/min through an ALU housing optimised for solvents, fuels, oils and non-aqueous hydrocarbons. It represents a significant step up in performance: stroke volume increases to 700 cm³, maximum solid passing rises to 7.5 mm, and viscosity ceiling reaches 35,000 mPas — suited to the most demanding bulk transfer operations in ATEX Zone 2 environments. Where PP or PVDF housing is required at the same flow and performance level, see the JP-810.171.

Purpose

The AODD operating principle means compressed air alternates between two chambers, driving a pair of flexible diaphragms back and forth. No electric motor contacts the fluid zone — making the JP-810.160 inherently safe for flammable and explosive media classified for ATEX Zone 2. The pump is fully self-priming, can run dry without damage and handles media containing suspended solids up to 7.5 mm. For applications involving high-viscosity media that require pre-heating before transfer, the pump pairs well with a HeatXperts drum heater to reduce viscosity to pumpable levels.

ALU housing — application range

The ALU housing is suited to solvents, fuels, oils and non-aqueous hydrocarbons — media that are incompatible with polymer housings (PP or PVDF) but where stainless steel is unnecessary or cost-prohibitive. The standard internal configuration uses an NBR/Santoprene diaphragm with stainless steel seats. Contact us for configuration advice specific to your medium and operating conditions. For highly aggressive aqueous media, oxidising acids or pharmaceutical applications, the JP-810.171 with PP or PVDF housing handles the same flow rate.

Key features

• AODD operating principle — no electrical components in the fluid path, inherently safe for flammable media
• Dry-running capable — no mechanical seal, no damage if air supply continues with empty chamber
• Self-priming — pulls liquid from 5 m dry or 9.8 m wet suction lift without manual priming
• Passes solids to 7.5 mm — large-bore ball-check design handles heavily loaded or slurry media
• Adjustable flow and delivery head via inlet air pressure — no frequency inverter required
• Non-lubricated air operation — no oil separator required in the air supply line
• Separable manifold — allows two different media to be pumped simultaneously
• Easy field maintenance — modular design, standardised spare parts kit available

Typical media — ALU housing

• Solvents, fuels and hydrocarbons — non-aqueous media compatible with aluminium
• Mineral oils, lubricants, hydraulic fluids and gear oils
• Aromatic and aliphatic solvents (toluene, xylene, hexane)
• Kerosene, diesel fuel and heating oil
• Paints, varnishes and thinners in production environments

Applications

• High-volume solvent and fuel transfer from IBCs and bulk tanks — ATEX Zone 2 environments
• Transfer of viscous hydrocarbon media including heavy oils, resins and bitumen precursors
• Production-rate drum and IBC emptying of solvents, fuels and lubricants
• Slurry and suspended-solids handling — 7.5 mm passing diameter accommodates heavily loaded media
• Offshore and petrochemical operations requiring high-flow ATEX-certified transfer
• Paint and coating production — high-volume supply of thinners, solvents and binders

Operational Requirements

• Air supply must be clean, dry and non-lubricated — do not use lubricated air (damages internal seals)
• Inlet air pressure must not exceed 8 bar — operating above rated pressure reduces diaphragm life
• Can be run dry without damage — no minimum flow requirement
• Ensure fluid connection piping is adequately supported — do not use the pump housing as a pipe anchor
• If the pump is stalled (air on, no flow), the diaphragm is under constant load — avoid prolonged stall conditions
• Verify chemical compatibility for aluminium for the specific medium and temperature before commissioning
