Stainless Steel Pneumatic Diaphragm Pump

We manufacture premium stainless steel Air Operated Double Diaphragm Pumps holding MD-CE certification for European markets. These pumps aren't just corrosion-resistant, we build them tough from 304/316L stainless steel because we know industrial demands inside and out. Running our own factory means we cut out middlemen costs which is how we consistently deliver solid value without ever compromising the quality you expect from us.

You might have seen our stainless steel pneumatic diaphragm pumps showcased at CIHF, CISMEF, or AIFME expos, the very same units that reliably move fluids without leaks and handle various suction jobs daily in the field. We design WYMA pumps for environments where other equipment struggles, such as dealing with harsh chemicals, continuous wastewater streams, or stringent food processing requirements. What helps our customers keep operations smooth is our guaranteed stock availability and fast shipping worldwide, combined with the fact that parts like bracket, air pressure regulate guage, multi-standard connectors(NPT, GB, BSP), oil pipe connectors, air hose, oil pipe, pneumatic tool lubricants, PTFE/Santoprene diaphragms and seals are straightforward to replace, alongside reliable after-sales support. And when you need technical questions answered, our support team responds.

Product’s Parameter (Specification)

Product’s Applications

Stainless steel air diaphragm pumps offer versatility across various industries:

‌Chemicals/Petrochem‌: Acids, alkalis, solvents, crude oil, grease.

‌Food/Pharma‌: Chocolate, syrups, extracts, ointments (FDA-compliant hygiene).

‌Mining/Construction‌: Coal slurries, cement, rock slurries, wastewater.

‌Electronics/Defense‌:Nitricacid,electroplating solutions,specialty explosive chemicals.

‌Coatings/Ceramics‌: Paints, pigments, clay/kaolin slurries (high-viscosity handling).

‌Metallurgy/Foundry‌: Metal slurries, hydroxide residues (abrasion-resistant).

‌Water Treatment‌: Lime sludge, sewage, corrosive effluents.

‌Automotive/Furniture‌: Polishing emulsions,varnishes,adhesives(hazardous media safety).

Made of 304/316L stainless steel, these pneumatic diaphragm pumps are ideal for pumping toxic, explosive, or heat-sensitive fluids. Their leak-proof design ensure reliable operation in extreme environments, from pharmaceutical clean rooms to explosive petrochemical areas.

Product’s Feature And Details

Enhanced Safety Features

This Stainless Steel Air Diaphragm Pump runs exclusively on compressed air that inherently makes it electric spark-free and eliminates ignition risks caused by heating. Running without liquid (also called dry running) won't damage it, preventing unexpected failure during operation. The precision-built metal silencer keeps operation quiet, but what matters more is its role in achieving triple explosion-proofing.

Durability and Performance Excellence

The pump body withstands high temperatures and demanding environments reliably. It handles variable inlet air pressure effectively, so it won't stuck during operation. The housing and screws use genuine imported 304/316L food-grade stainless steel that's the standard for enduring high temperatures and resisting chemicals. We use German imported PU for the diaphragms and US imported PU for critical seals because they deliver longevity. The heart of the pump – diaphragm, uses imported PTFE/Santoprene because it simply doesn’t crack. These materials integrity ensure hygiene and operational reliability where it counts. That means the pump typically lasts 3X longer and delivers ISO-certified 3X leak-proof performance that requires significantly less maintenance than alternatives. Benchmarks show its air chamber generates suction power 40% stronger than typical competitor equivalents.

Convenient Cleaning Maintenance

How do you ensure no residue? This Stainless Steel Pneumatic Diaphragm Pump features easily disassembled inlet and outlet pipes design that clean thoroughly so you won't encounter trapped material. Maintenance is simple and convenient: Only need to drip 2 or 3 drops of pneumatic tool lubricants into the air inlet before and after use and then idle for a few seconds to complete the maintenance, so that the equipment can run stably for a long time.
