What You Didn’t Know About Double Disc Pumps

Can a Double Disc Pump Have Ball Valves? Yes. In fact, ball valve technology is helping to usher in the next era of double disc style pumps. The ball valves help to break up solids and make pumping thicker municipal sewage easier. The ball valves also make it much easier to maintain the pump.

Diaphragm Pump for Sewage Pumping

Primary sludge pumping from digesters

A WWTP just expanded and upgraded their pump facilities. The facility chose double diaphragm pumps to transfer sewage from digesters for secondary treatment. Project participants included Mud Sucker Diaphragm Pumps and pump manufacturer Wastecorp Pumps.

Waste Containment Pump Systems | Your Options

Personal waste containment systems or “honey wagons” as they are sometimes called in the pump industry have come along way in just the last few years. In response to the soaring costs of vac truck services, everyone from those needing septic pumping, waste oil pumping and used vegetable oil transfer have found an economical alternative in owning a personal waste containment systems.

Membrane Bioreactor System (MBR) Pump Component Supplier

MBR pump system















Wastecorp is proud to be a global supplier of pump systems for manufacturers of membrane bioreactor systems or MBR’s. MBR’s have become a popular for small footprint new wastewater treatment systems in both the municipal and industrial sewage treatment spaces. Manufacturers of membrane bioreactors use Wastecorp pump products for the activated sludge pumping process.

What Kinds of Pumps Are Needed For MBR’s?

When designing an MBR today it is almost critical to have pumps made by an ISO 9001 and ISO 14001 certified pump manufacturer who also adheres to hydraulic institute standards. This helps to ensure that the pumps have a track record, are of high quality and have been properly tested prior to installation in the MBR and customer use. MBR’s typically work with suspended solids, settlement separation systems, mixed liquor and concentrated waste products. The types of pumps available for mbr’s depend on the type of application:

MBR Mud Sucker Diaphragm Pumps Systems
One of the most popular pumps selected for inclusion in a municipal or industrial MBR is the Mud Sucker diaphragm pump. MBR manufacturers have specified this pump for the last few years and it is growing tremendously in popularity. First there is a wide product offering for either municipal or industrial MBR’s. Select from 1.5”-4” connection sizes with activated sludge handling capabilities up to 220 GPM depending on the model selected. Mud Sucker pumps are adaptable for mobile and stationary MBR’s. Electric, engine, air or hydraulic drive systems are available without significantly increasing the cost of the pump. Mud Sucker pumps are extremely cost effective pumps that are simple to use and service. Engineers and operators love them. Repair parts are relatively inexpensive when compared to alternatives.

MBR Plunger Pump Systems
For heavier activated sludge transfer requirements for membrane bioreactor systems Sludge Master plunger pumps have become a popular option especially for thick slurry pumping. The manufacturer recently launched a small footprint model called the Sludge Master Space Saver that can fit into a compact MBR.

MBR Sludge Pro Double Disc Pumps
For a less maintenance intensive MBR pump product the double disc pump is a popular option for higher solids and sludge concentrations. The double disc pump is part of the diaphragm pump family so, the double disc pump is essentially a more robust version of a diaphragm pump. Solids management happens with either a clack valve (flapper) or check ball system which is up to the MBR manufacturer or engineer to decide. The factory can provide support in selecting which is more ideal.

Double Disc Pumps and Municipal Sewage Pumping

For years, we have been asking wastewater treatment plants (WWTP) what they like about double disc pumps and what they don’t like. We have even been compiling a database with what regions of the USA and Canada have success with this type of pump for sewage and which areas have had more challenges.

One of the things that most WWTP’s say is that there has been limited competition in the specifications put out for bid by municipalities and consulting engineers working on wastewater projects. As we all know a monopoly in the pump industry is seldom a good thing for quality, innovation and of course pricing for pumps and parts.

Food Waste Pumps – Food Processing Facilities

The challenge for food waste processors is finding pumps for their applications that are versatile and robust enough to pump through a variety of conditions. This was just the case for a Fresno, California based alternative energy company who earned a multi-year contract to accept expired and spoiled canned tomato paste, tomato sauce, fruit juice, ketchup and bulk tomatoes for Fresno and Bakersfield area grocery stores, prisons, hospitals, food preparations companies and more.

New Space Saving Double Disc Pump

A new double disc pump for sewage and sludge pumping at municipal WWTPS.

We recently asked municipal operators who had either a Penn Valley double disc pump or Wastecorp Sludge Pro double disc pump what they would like to see in future product offerings for sewage pumping. The overwhelming response was a compact fit with easy-to change parts when needed.

Wastecorp spent years in research and development designing a new type of double disc pump that provides both engineers and operators an option with low maintenance double disc pumps. We have fielded endless calls from operators over the years complaining about the high cost of rotary lobe and progressive cavity pump parts. While the initial cost may be lower for the pump, the final cost when incorporating parts costs throughout the lifecycle can end up being tens of thousands more than other sewage pumps.

Wastecorp is thrilled to announce the launch of the new easy-to-use Sludge Pro Space Saver Double Disc Pump. The Sludge Pro is designed to pump municipal sewage, industrial wastewater and solids and much more. The Space Saver can pass 2 1/2” spherical solids on all  3”, 4” and 6” connection sizes thanks to Wastecorp’s robust full port ridged clack valve technology.

Penn Valley double disc pumps are only able to pass 1” solids on a comparable 4” pump and requires an extensive disassembly process to replace the discs and trunnions. You can see the differences in the Sludge Pro and Penn Valley in a new comparison video.  

Replacement of the disc and trunnion on the space saver is an easy process since the drive shaft remains in place during the entire procedure.Your selection of double disc pump models has become much larger in recent years. You no longer have to settle for one brand or manufacturer. Contact double disc pump manufacturer Wastecorp today to receive pump performance curves, engineering drawings or specifications for your upcoming project. 1-888-829-2783 or

What Is It?
The Space Saver double disc pump is a type of sewage pump designed to pump municipal wastewater and sewage.

Where Is A Double Disc Pump Installed?
A double disc pump is installed typically at a municipal wastewater treatment plant, landfill or industrial solids pump processing facility. At a WWTP the Sludge Pro typically sits in the basement near the digesters or primary sewage pumping area. In modern day applications, the double disc pump may have a grinder or some other screening method of sewage

What Size Solids Can The Sludge Pro Pass?
The sludge Pro can pass up to 2.5″ solids, compare that to about 1 inch solids for the red kind.

When is The Sludge Pro Space Saver Available?
The sludge Pro is available now.
