Diaphragm Pumps

Handling abrasive slurries or corrosive chemicals often leads to frequent pump failures and line shutdowns. Our Diaphragm Pumps support flows up to 1,000 L/min and pressures up to 120 bar across diverse media.

Flow Rate Range

0.1 L/min to 1,000 L/min (0.026 GPM to 264 GPM) – Pulsation dampeners available

Pressure/Head Capacity

Up to 120 bar (1,740 psi) – Air-operated models: 8.6 bar max (125 psi)

Power Requirements

0.1 kW to 30 kW (0.13 HP to 40 HP) – Electric models Air Consumption: 0.3–10 m³/min (10–350 CFM) for AOD pumps

Materials of Construction

Pump Head: PP, PVDF, SS 316, Hastelloy Valves: PTFE, EPDM

Fluid Compatibility

Corrosives, Slurries, Abrasives, Viscous Fluids – Handles acids, solvents, and shear-sensitive media

Product Description

These pumps run dry without damage and can handle up to 80% solids, giving buyers flexibility in system design. Available in multiple configurations, these pumps meet cleanroom, chemical, and industrial duty requirements with air or electric actuation options.

Temperature Range

-40°C to 180°C (-40°F to 356°F) – Higher temps with specialty diaphragms

Connection Types & Sizes

Flanged (ANSI/DIN), Threaded (BSP/NPT), Tri-Clamp (Sanitary) – Sizes: 6 mm to 100 mm (¼” to 4″)

Mounting Configuration

Horizontal or Vertical – Skid-mounted, frame-mounted, or portable designs

Diaphragm/Tube Material

PTFE, EPDM, Metal (Hastelloy) – Double diaphragms for leak-proof operation

Efficiency Rating

45% to 70% (lower for air-operated/AOD pumps)

NPSH Required

Self-priming – Can lift up to 6 m (20 ft) dry and 4 m (13 ft) wet

Speed Range

20 to 300 strokes/min – Adjustable for flow control

Solids Handling Capability

Passes solids up to 50 mm (2″) and slurries with 80% solids content

Certifications & Standards

ATEX, FDA, 3A, EHEDG, ISO 9001 – Compliant for food, pharma, and hazardous areas

Operating Noise Level

< 75 dB(A) (electric models) / < 85 dB(A) (AOD models)

Coupling System

Direct Drive (Crankshaft) or Air Motor (AOD pumps)

Technical Advantages

Many fluid systems face wear, leakage, or cavitation under changing loads or fluid types. Our Diaphragm Pumps support up to 70% efficiency and can lift fluids dry up to 6 meters, ensuring steady output.
We provide options in PTFE, EPDM, or Hastelloy with flanged, threaded, or sanitary connections to match your plant layouts. With adjustable speeds from 20 to 300 strokes per minute and noise levels under 85 dB(A), they integrate cleanly into both indoor and mobile systems.

Industry Applications

Chemical Processing

Transfers acids, solvents, and reactive media with non-metallic or exotic alloy pump heads.

Food and Beverage

Supports sanitary flow with Tri-Clamp ends and FDA/3A-compliant wetted parts.

Pharmaceutical Plants

Moves shear-sensitive or sterile fluids using leak-proof double diaphragm setups.

Mining and Slurry Handling

Transfers heavy solids or abrasive mixtures with thick diaphragms and reinforced internals.

Paint and Coatings

Delivers smooth, pulsed flow for high-viscosity paints with air-actuated flow control.

Water Treatment Systems

Handles polymers, sludges, and chemical dosing with consistent output under varying loads.

Pumps Configured for Your Fluid Demands

Every facility has different demands for flow rate, fluid behavior, and installation space. Our Diaphragm Pumps support horizontal or vertical setups with portable, frame, or skid-mounted bases for easy placement.
We configure couplings and diaphragm materials to suit your pressure, speed, and chemical handling needs. This helps you avoid frequent changeovers or performance drops, giving consistent output across operating shifts.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match the pump material with my chemical media or slurry mix?

Yes, we review your process fluid details and suggest suitable combinations of PP, PVDF, SS 316, or Hastelloy for the pump head. Valve and diaphragm materials like PTFE or EPDM can also be changed based on temperature or reactivity. This helps avoid frequent replacements or seal failures during operation.

Do you offer diaphragm pumps in specific mounting or space-constrained configurations?

We support horizontal or vertical layouts with skid, frame, or compact portable designs. Connection ends can be flanged, threaded, or Tri-Clamp based on your system requirements. Before dispatch, we share GA drawings for approval to match your plant layout.

What control options do I have for flow variation or batch-based dosing?

We can provide adjustable stroke rate settings and air motor configurations that respond to pressure changes. For electric models, flow control can be integrated via VFDs or stroke timers. These options allow steady output across multiple operating shifts.

What is your typical lead time and can you support staggered delivery based on our project phase?

Lead times range from 2 to 6 weeks depending on size, materials, and quantity. We support staggered shipments if you confirm your schedule during order confirmation. This helps align with phased installations or inventory planning.

Can you adjust internal clearances or diaphragm thickness to match our slurry composition and operating hours?

Yes, we can change diaphragm thickness and clearance settings based on your solid content and abrasion level. We use different wear-resistant materials for longer duty cycles. Our team confirms these parameters before finalizing the build.
