Using an electric motor to drive the diaphragms results in electric diaphragm pumps having improved energy efficiency and control. They can be programmed for precise metering and dosing, and they offer the same convenient self-priming ability as other double diaphragm pumps. Wastecorp electric diaphragm pumps are available with standard single-phase electric, three-phase electric, and explosion-proof motors


Electric Diaphragm Pumps

Engine-driven diaphragm pumps are motor driven, and rely on fuel, rather than electricity, to drive the pump.. (A diesel double diaphragm pump, for example, is run on diesel.) The use of fuel allows engine diaphragm pumps to handle high-pressure flows better than other types of diaphragm pumps, making them ideally suited to work in quarries and construction sites

Engine Diaphragm Pumps

Mud Sucker® double diaphragm pump systems are available in a wide variety of configurations, including 1.5” diaphragm pump, 2-inch double diaphragm pump, 3-inch diaphragm pump, and 4-inch double diaphragm pump sizes, and they have fluid handling capabilities ranging from 40-220 GPM. Our double diaphragm pumps can be adjusted to handle different flow rates and fluid types, allowing you to complete multiple tasks with one pump.

Double Diaphragm Pumps

Air-operated diaphragm pumps (AOD) and air-operated double diaphragm pumps (AODD) are recommended for processing flammable liquids because they don’t provide a source of ignition. AOD pumps are frequently used during petrochemical production and chemical processing. At Wastecorp, our AOD pumps come in a wide range of diaphragm pump materials, including stainless steel diaphragm pumps, to facilitate the transfer of abrasive and corrosive liquids.

AOD Pumps

Hydraulic pumps use operating fluid, such as oil or liquid silicone, to transmit power from the motor to the diaphragms. Hydraulic pumps contain built-in safety features, such as a pressure relief mechanism, that allows them to handle very high-pressure applications. These pumps are often used in the petrochemical industry.

Hydraulic Diaphragm Pumps

Wastecorp’s heavy-duty grout pumps are suitable for a wide variety of grouting applications, such as waterproofing and masonry repair. Our grout pumps can be operated manually or with compressed air, giving you the flexibility to move around job sites freely. With their enhanced durability, they can handle even the thickest and most challenging grouting materials, including cement grouts. 

Grout Pumps

Hand pumps offer the ultimate portable pumping solution, allowing users to transfer fluids anywhere without needing an external power source. Wastecorp hand pumps combine lightweight materials with the latest innovations, like BUNA-N flappers and diaphragms, to produce pumps that are both highly durable and easy to transport. Hand pumps can be used in remote locations or for specific applications, such as priming other pumps.

FAQs

Diaphragm Pumps - Questions and Answers


What is a diaphragm pump?

A diaphragm pump (also called a membrane pump) is a type of positive displacement pump that uses suction to transfer liquids. The flow of liquid is controlled with either a flapper or a ball valve and driven by the reciprocating action of the diaphragms. As the diaphragms move back and forth, they create negative air pressure in the pump chambers, drawing in and expelling liquid in a consistent rhythmic pattern.

Because diaphragm pumps do not use an impeller, they are very versatile. If you have an air operated diaphragm pump (AOD) cases, you will require an  air compressor to operate a the pump. If you have an electric or engine driven pump you will require either 120V, 460V or gas, diesel, propane or natural gas. Unlike centrifugal pumps, diaphragm pumps are self-priming and can withstand significant variations in volume, flow rate, and viscosity.

What types of diaphragm pumps are available?

Diaphragm pumps come in four principle configurations: electric, engine, manual, air-operated or hydraulic.

Air-operated diaphragm pumps use compressed air to move the diaphragms back and forth, allowing them to operate virtually anywhere. Electric diaphragm pumps, on the other hand, are powered by an electric motor. They’re highly energy-efficient and capable of precision dosing, making them the preferred choice for some industrial applications. Similar to electric diaphragm pumps, engine pumps are driven by a motor. However, the motor in an engine pump runs on fuel rather than electricity.

In a hydraulic pump, the diaphragms are driven by pressurized hydraulic fluid. The hydraulic fluid creates counter-pressure, which gives these pumps superior resistance to high pressures and flow rates.

What kinds of fluids does a diaphragm pump transfer?

One of the main advantages of using a diaphragm pump is the incredible variety of fluids these pumps can transfer. Some of the many fluids a diaphragm pump can transfer include wastewater, mineral slurries, food and beverage products (such as milk, yogurt, syrups, fillings and sauces), non-combustible oil, paint, chemical solutions (e.g., herbicides and pesticides), resin compounds, and adhesives.

Diaphragm pumps can handle high-viscosity liquids and liquids with a high percentage of suspended solids without stalling, clogging, or sustaining damage. They’re also appropriate for use with shear-sensitive liquids.

What sizes of diaphragm pumps are available?

Diaphragm pumps are available in connection sizes ranging from 1-4 inches, with larger connection sizes being preferred for tasks where a high flow rate is required. Couplings are available to fit almost any piping arrangement.

Can I customize my diaphragm pump? 

At Wastecorp, we offer comprehensive Mud Sucker brand diaphragm pump customization services. Customers can choose from multiple diaphragm pump materials and configurations, with several options available for handling highly corrosive and abrasive liquids. In some cases, customers can also select different motors, ball valves, mounting options, drive options, and more. 

Are there additional accessories I can add to my pump?

Absolutely! We offer numerous accessories to extend the functionality of your pump, making it possible to use one pump for multiple applications. Most of our pumps also come with the option of ordering a spare parts kit, making routine maintenance easier and more convenient. 

How do I get a quote for a diaphragm pump?

What are some common issues and fixes for diaphragm pumps?

Most of the time, diaphragm pumps operate smoothly – even in challenging conditions. However, worn parts or installation errors can cause performance issues or cause the pump to cease functioning altogether. Some common problems encountered during diaphragm pump operation and their solutions are as follows:

- Pump fails to cycle, or cycles once and stops. Check for worn or damaged valve balls, seats, or o-rings and replace them as needed. If the pump is in good condition, make sure the air valve is clean and unobstructed and verify that the pump is not over-pressurized. If the pump is under too much pressure, install a pressure relief valve.

- There are air bubbles in the liquid being expelled. Look for loose parts, paying close attention to the suction line, manifold and manifold seals, and O-rings. If there are no loose parts, this problem may indicate the diaphragms need replacing.

- The pump air valve freezes. This issue usually indicates there is too much water in the pump’s air supply. Take steps to reduce moisture content in the compressed air, such as by installing a dryer or filter. 

- Air is leaking from the pump. Tighten the air valve cover and replace any worn gaskets. 

- Fluid is leaking from the pump. Tighten the manifold bolts and inspect the seal between the manifold and seat. Replace seats and O-rings as needed. 

- Pump is not achieving prime. Try reducing the air inlet pressure. If that does not work, inspect the pump’s outlets and inlets to make sure they are open and not clogged with debris. If the pump still will not prime, you may need to replace the check valve ball and seat or the manifold O-rings. 

What are the best industrial applications for diaphragm pumps?

Diaphragm pumps are used across many different industries owing to their versatility, efficiency, and durability. Some of the top industrial applications for diaphragm pumps include wastewater treatment, manufacturing, food and beverage processing, agricultural spraying, building and construction, mining, and oil and gas production. Diaphragm pumps are also used in the pharmaceutical, automotive, transportation, and aerospace industries. 

As well as manufacturing pumps for industrial uses, WasteCorp supplies pumps to small businesses (such as hotels, restaurants, and marinas) and provides pumps to homeowners who need them for water removal or DIY projects.
