City of Brocton, New York filter press feed project – 27 years of reliable pumping service and counting

In Chautauqua, the westernmost county in New York State, lies the quiet village of Brocton.  Although an unassuming little town, it boasts the birthplace of the designer of the Pullman Sleeping Car, George Pullman, and offers some of the best wines from surrounding Lake Erie Wine country.

The Village of Brocton Water Pollution Control Facility (BWPCF) was built in 1983. It was originally designed to treat 237,000 gallons of wastewater per day with a number of upgrades completed over the past 30 years to treat additional wastewater from a growing community and the Department of Corrections Lakeview Shock Facility.

These upgrades have made the facility one of the most modern wastewater treatment plants in the area, with a capacity of 658,000 GPD. Today, the facility utilizes the technology and treatment parameters of Active Sludge, by means of Sequencing Batch Reactors (SBR’s). The wastewater is treated in a number of phases, all handled by only three full time employees.

In 1988, an ABEL model CM piston-diaphragm pump was purchased and installed as an integral component of the sludge dewatering system. The pump takes the underflow from the clarifier and sends the thickened solids to a high-pressure (225 psi) plate and frame filter press.  

As pressure begins to build in the filter press, the pump’s CPR valve throttles back on the amount of hydraulic fluid supplied to cylinder between the piston and diaphragm.  With less fluid in the cylinder, the stroke length of the diaphragm is reduced, thus decreasing flow. This inherent design of the model CM pump, mechanically reduces the flow as pressure increases without the requirement of Variable Frequency Drive (VFD).  In addition, the decrease in hydraulic output results in a drop in the required electrical power required by the motor, thereby saving money.  


•  High reliability where prolonged continuous duty is required
•  Low wear with ideally rated diaphragm and product valve materials
•  Up to 95% volumetric efficiency thanks to unique shape of diaphragm and housing
•  Low maintenance due to minimal wear
•  Dual-diaphragm design with leakage detection ensures reliability
•  Hundreds of filter press feed installations world-wide
•  Quality assurance according to ISO 9001



As of 2015, The ABEL model CM pump continues to deliver reliable service in its 27th year



The CM pump excels at high pressure and abrasive duty applications including thickener/ clarifier underflow and primary sludge transfer




Spray Dryer Feed for Tungsten Slurry at GTP


Serenely situated on the banks of the Susquehanna River in northeastern Pennsylvania is Global Tungsten & Powders Corp (GTP)a leader in the manufacture of ready-to-press tungsten carbide powders. These specially formulated powders are crucial in the manufacture of cemented carbide parts for specialized cutting tools and metal working components.  Many of GTP’s customers cater to the mining and oil & gas industry.

To produce the proper size Tungsten carbide and cobalt powder, a recipe is mixed in day tanks and fed to spray dryers where the carrier liquid is flashed-off. The water born slurry is very abrasive and viscous with an s.g. of 4 kg/l and pumped to the spray dryer at a rate of about 700 kilo slurry per 4 hours.


The nozzle in the spray dryer produces backpressure of about 250 psi, and the combination of the flowrate, pressure and abrasive duty makes for a very difficult pumping application.

The original feed pump used to feed the spray dryer was a pulsing type pump with a fast stroke rate.  The facility found themselves replacing diaphragms or “tubes” every few days.  The high wear parts usage, excessive maintenance and downtime was not only tedious but very costly.  Something had to be done.

The ABEL Solution.
High pressure, abrasive slurry and low flow rate led to the selection of ABEL’s model CM pump as the best choice to resolve this pumping challenge.  Here is how…



The wear components in the ABEL model CM spray dryer feed pump include these Ball Checks and Seats, which are easily accessible and simple to replace. The elastomer ball has a solid steel core which helps establish a firm seal in slurries. This makes the CM one of the most efficient pumps in the industry.


The Compact Membrane (model CM) pump for spray dryer feed employs ABEL’s piston-diaphragm technology (sometimes referred to as hydraulic membrane technology). The piston is capable of producing the resultant pressure induced by the spray dryer nozzle, and the diaphragm shields the piston from direct contact with the slurry. While slurry can score the cylinder liner and abrade the piston seals in other piston pumps, the ABEL CM technology utilizes a hydraulic end which separates and isolates the internal pump components from the slurry, and limits wear to the elastomer components (diaphragm, check balls and check seats), which are very durable and easy to install and replace.   The end result has reduced maintenance to every 4-6 months instead of every few days, saving money, effort and downtime.   
In addition to ease of maintenance, the model CM piston-diaphragm pump incorporates dual diaphragms which provide additional security in the event of a worn diaphragm or diaphragm breach. A leakage detection port between the diaphragms indicates if slurry is present and signals the pump to shut down before damage can occur.  

The ABEL Advantage
•  Compact design (small footprint)
•  Air tight pump system with no leakage on the floor
•  Low wear due to piston-diaphragm technology
•  High efficiency due to diaphragm design and shape
•  Lowest operating and life-cycle costs
•  Only one piston, promoting less wear
•  Ease of maintenance

Today, all over the world, manufacturers and OEM’s use hundreds of ABEL CM pumps for their Spray Dryer applications. With a growing list of satisfied customers, that’s why we say we are willing and “ABEL to handle it”.
