Picking the wrong diaphragm pump manufacturer does not just cost money; it costs uptime. In 2025, diaphragm pumps represent around 27% of the global positive displacement pump market, and the number of suppliers keeps growing. So how do you sort the proven from the overpromised?
We put together this list based on product range, industry track record, after-sales support, and real-world performance in tough applications like mining, chemical processing, and wastewater. Here are 10 diaphragm pump manufacturers worth your shortlist.
If you’re in mining, you’ve probably heard the name GEHO. Weir Minerals Netherlands has supplied its 1,000th GEHO piston diaphragm pump since it started the engineering and manufacturing of these pumps in 1968 for the transportation of ores, minerals, and tailings.
Their GEHO piston diaphragm pumps handle abrasive slurries and sludges of medium to high viscosity or corrosive material at high temperatures, with up to 98% availability and outstanding efficiency. That kind of uptime record is hard to argue with.
ABEL Pump Technology has been developing and manufacturing highly engineered pump solutions for abrasive, toxic, and viscous media since 1947, supplying piston diaphragm and high-pressure piston pumps in more than 60 countries worldwide.
What stands out? Their electric diaphragm pump achieves an energy efficiency of up to 90%, requiring significantly less energy than air-operated diaphragm pumps. And they’ve recently rolled out an AI-powered Smart Pump Assistant for predictive maintenance, showing a forward-thinking approach for a company with over 75 years of history.
For more than 60 years, HMH has been manufacturing Wirth™ piston diaphragm slurry pumps, with a full line of high-pressure slurry pumps that can cover every type of slurry application and have power ratings of up to 3,000 kW.
In 1968, they developed the first triplex single-acting piston diaphragm pump, which is now a standard technology in the transport of highly abrasive media. Solid legacy.
TOMINE manufactures a full range of mining slurry pumps and piston diaphragm pumps designed for mineral processing plants across the globe. Its double-hose piston diaphragm pump uses a two-hose design inside the pump chamber that effectively prevents slurry leakage into the hydraulic oil — no high-pressure sealing water needed.
The reciprocating hydraulic piston diaphragm pump handles solids content up to 70%, runs at 82–87% pump operating efficiency, and works for long-distance tailings and concentrate pipelines.
Beyond pumps, Tomine backs every project with beneficiation experiments, engineering design, installation, and technician training. This makes it a suitable option for operations seeking a more complete, system-level solution rather than standalone equipment supply.
Graco Inc. is a diversified manufacturer that offers a wide range of fluid handling equipment, including diaphragm pumps. Founded in 1926, Graco has grown to become a global leader, with products used in industries such as automotive, aerospace, and general manufacturing. Their AODD pumps are trusted across paint, coating, and chemical transfer applications.
Flowserve specializes in fluid motion control solutions and has expanded its portfolio to include diaphragm pumps, offering a range of industrial diaphragm pump products, making it a key player in this market. They’re a go-to for buyers who need a single vendor across multiple pump types.
Verder Liquids is a global player in the fluid handling industry, offering a wide range of diaphragm pumps. They use long-life components in the construction of their diaphragm pumps. Diaphragms, valves, and other parts are designed for extended service life, reducing the need for frequent replacement and maintenance.
Yamada Corporation is a Japanese company that has been manufacturing diaphragm pumps for many years, and their products reflect Japan’s reputation for precision manufacturing. Their diaphragm pumps are designed to be compact, making them suitable for use in applications where space is limited, such as in small-scale manufacturing plants or mobile equipment.
Emmerich is a specialist worth knowing. Their piston diaphragm pumps handle abrasive slurries at high pressures, meeting difficult requirements specified by the customer. Since 1975, Emmerich has maintained its own in-house production of rubber parts, including diaphragms, valve seats, and sealing rings, which gives it tight quality control over wear components.
Warren Rupp is committed to continuous innovation, investing heavily in research and development to improve products and develop new technologies, including improving the energy efficiency of their air-operated diaphragm pumps. They’re part of the IDEX Corporation family, which adds financial backing and global distribution muscle.
Not every manufacturer on this list is right for your project. Here’s what actually matters:
The diaphragm pump market is mature but still evolving. Manufacturers are introducing energy-efficient designs, longer-life diaphragms, and smart monitoring features, with IoT-enabled diaphragm pumps gaining popularity in large industrial setups where predictive maintenance helps reduce downtime. Whether you’re building a new concentrator plant or replacing worn-out equipment, the 10 manufacturers above have earned trust across mining, chemical, and industrial sectors.
If your operation involves abrasive ore, corrosive tailings, or long-distance slurry pipelines, the piston diaphragm pump deserves a close look, and TOMINE’s lineup is built specifically for these challenges.
What is a diaphragm pump used for in mining?
Diaphragm pumps, especially piston diaphragm models, move abrasive slurries, tailings, and mineral concentrates through pipelines. They’re applied for concentrate pumping, tailings pumping, filter press feeding, mine dewatering, and hydraulic ore hoisting. The diaphragm separates the slurry from drive components, which drastically cuts wear.
Are piston diaphragm pumps better than centrifugal slurry pumps?
Yes, for high-solid, high-pressure, and long-distance applications. Piston diaphragm pumps deliver consistent flow under high pressure and last longer on thick, abrasive media. Centrifugal pumps are better for lighter slurries with shorter pipe runs. Many plants use both in different stages.
How long does a piston diaphragm pump last?
Piston diaphragm pumps have a respectable service life due to the diaphragm, which separates drive and medium. Major wear components like gearboxes and drive pistons can last the entire life of the pump with proper maintenance. Diaphragm replacement intervals depend on media and operating conditions.
