In demanding industrial environments, not all pumps are created equal. If your operation involves aggressive chemicals, sludge, slurries, or abrasive fluids, you need a diaphragm pump that can stand up to the punishment and keep your business moving. At MultiTorque, we go beyond standard supply—we custom-build, repair, and maintain diaphragm pumps for clients across Australia.

From mining and wastewater to agriculture and food-grade industries, diaphragm pumps offer versatile, reliable pumping power. Our team specialises in delivering tailored solutions that are engineered for durability, compliance, and ease of use.

What Are Diaphragm Pumps?

Diaphragm pumps—also known as membrane pumps—are a type of positive displacement pump that uses a flexible diaphragm to move fluids. The diaphragm flexes back and forth, creating alternating suction and discharge cycles. Because the fluid is isolated from moving mechanical parts, diaphragm pumps can handle corrosive, abrasive, and viscous materials with ease.

They are ideal for transferring fluids that would destroy or clog conventional pumps, making them the preferred option in tough and hazardous settings.

Why Choose Diaphragm Pumps?

Diaphragm pumps are widely used for several key reasons:

• Self-Priming: Handles air and dry starts without damage

• No Seal Failures: Fluid chamber isolated from moving parts

• Handles Solids: Passes slurries, sludge, and particulates

• Chemically Resistant: Excellent with acids and caustics

• Portable Options: Trailer and skid-mounted systems available

• Low Maintenance: Fewer wear components = longer uptime

These pumps are commonly used in industries that require dependable fluid transfer with minimal risk of leakage or breakdown.

Custom Diaphragm Pump Builds by MultiTorque

MultiTorque doesn’t just sell pumps—we engineer custom diaphragm pump units designed to handle your unique challenges. Whether you need a generator-powered trailer-mounted diaphragm pump or a compact portable unit for remote locations, we build it in-house to exacting standards.

Our custom setups can include:
