Positive Displacement Pump I.

Background: Development of the AMA Positive Displacement Pump began in 2001 out of frustration with the operating, maintenance cost and downtime caused by the in-effectiveness of the pumps used in wastewater applications. Wastewater plants have several applications for solids handling pumps to transfer bio-solids and waste products throughout the entire treatment process. A typical treatment plant will have applications for grit removal pumps, scum removal pumps, gravity belt thickening pumps, gravity belt discharge pumps, portable trash pumps and lagoon dewatering pumps to name a few. Pumps used in these applications have a long performance and maintenance history and as expected some pumps perform better than others. However, no matter how you evaluate the different pump technologies that are used, they all have common problems. Grit, rags and other solids materials are the number one cause of pump failures. The unpredictability of the failures has led to tremendous capital, maintenance and operational cost for the wastewater industry. AMA’s solution was to develop a new pumping technology that would allow the grit, solids and stringy materials to pass through the pump without damage and the pump’s effectiveness had to meet or exceed the performance of other technologies in terms of downtime, operating cost and maintenance. The AMA Positive Displacement Pump Model SF28X-H6 has met that goal and has demonstrated the following results: · Delivers a flow rate at a given pump speed independent of suction (20ft of lift) and discharge (70 ft of head) pressures. It is a true positive displacement pump. · Flow rate can be increased or decreased by simply changing pump speed (150 gal/min @ 45 strokes/minute) · Run dry without damage and will start pumping when liquid is introduced without priming. · Designed for ease of maintenance and operation · Lowest maintenance and operating cost · Available in stainless steel or ferrous steel construction · Easily passes solids such as sand, gravel, stringy materials, straw, feathers, scum and gloves.

What is the AMA Positive Displacement Pump ·

The Technology: AMA pumps has developed and patented a pump specifically for solids handling applications found in industries dealing with waste stream byproducts. This simple yet innovative, positive displacement pump’s flowthrough non-clog design allows entrained solids, viscous sludge, rags, and other types of solids to easily pass through the pump while imparting negligible shear. The concept behind the technology is to create a pumping action by displacing volume through a series of check valves. The AMA Model SF28X-H6 Positive Displacement Pump is a hydraulically driven pump constructed from stainless or ferrous steel. The pump delivers up to 150 GPM at 45 strokes per min against a discharge pressure of 70 ft and a lift of 20ft. Its unique design features many advantages that allow versatile configurations or layouts.

How does it Work:

Workings of the AMA Pump Pressure Switch used to continuously monitor internal pressure of the flexseal. Low set point will shut pump off indicating tear in flex-seal. High set point protects pump from blockage in discharge pipe.

Hydraulic drive unit is the power behind moving the flexseal in a reciprocating motion for the 3” displacement

Inlet Check Valve Opens during the up stroke and closes on the down stroke of the flex-seal.

Opens during the down stroke and opens on the down stroke of the flex-seal. Opposite of inlet.

The key component to the pump that creates the pressure to displace the volume throughout the entire stroke. The flexseal is made up of two identical halves mirrored together to form a bladder. This cavity is energized with air to maintain a constant pressure against the reinforced rubber. Keeping the rubber in tension at all times is the key to longevity. How long does an under inflated tire last? The rubber material in the flex-seal is designed to maintain 30 PSI at a 3” total stroke for 3000 hours. The 30 PSI is the limiting factor for how far and how high this pump can move the liquid from the pump to the discharge point. Not correcting for losses due to pipe and fittings, this means you can pump water straight up to a height of 70 feet (equivalent unit of measure for 30 PSI). The conversion formula is for every 2.31 feet of elevation and is the same as 1 PSI. As long as the discharge pressure is less than 30 PSI, the pump will perform at rated capacity and longevity.

Positive Displacement Pump III. How does it Work Continued: ·

Flex-Seal: A proprietary material combines elastomer and fabric for a high strength, flexible composite that can be molded and vulcanized into the shape used to create the primary pumping element for the pump. Energized with air, the flex-seal is kept in constant tension throughout the stroke, regardless of suction or discharge conditions. Maintaining constant interior pressure on the flex-seal material and allowing the air to compress throughout the stroke prevents premature failure of the elastomer and greatly increases longevity of the flex-seal. The flex-seal technology also makes it possible to displace a greater volume throughout the reciprocating stroke resulting in higher gallons per stroke. With a 3-inch stroke, the pump is capable of pumping 150 GPM at less than 45 strokes per minute, which greatly increases the mechanical life of the pump.

·

Check Valve: The pump utilizes pinch-valve technology that can be provided by various manufacturers. AMA chose to use the Series 37 in-line check valve manufactured by Tideflex based upon 20 years of proven performance in the industry. The pinch-valve type of check valve has superior qualities to that of other types of valves such as ball or swing check valves. Entrained solids, viscous sludge and rag-type or other solids easily pass through the pinch-valve without concern of maintaining proper seal.

Pressure Switch (Optional): The WIKA CP3000 is a dual set-point pressure switch that continuously monitors the internal pressure of the Flex-seal. Once the Flex-seal is energized with air, the pressure switch will stop the pump if subjected to adverse conditions. Discharge blockage or a closed valve will cause the Flex-seal pressure to increase and trip the high set point and shut down the pump. Likewise, if the suction conditions or loss of air cause a decrease of pressure in the Flex-seal the low set point will trip and shut down the pump.

Features and Benefits: ·

· ·

· ·

Ease of Maintenance: A vital design component and feature of the pump is the simplicity of operation and ease of maintenance. All service components of the pump are easily accessible and no special tools are required to service and maintain the pump. The pump can be serviced in place with minimal downtime. Run-Dry: The Flex-seal and check valves can operate continuously under noflow conditions without damage. No run-dry protection is required. Priming: If the pump is installed for a suction lift, it requires an initial filling (priming) of the pump cavity with water. Once primed, the geometry of the pump allows air to move through so that it maintains a prime at all times. Applications that draw from a pit or tank can remove product down to the suction inlet and pull in air without the need to re-prime the pump. When the liquid level rises above the suction inlet, the pump will resume pumping. Built-in Protection: The use of the optional WIKA Dual Pressure Switch/Gauge to protect the pump from excessive high or low pressures in the Flex-seal protects the pump from damage. Controls: The hydraulically driven pump is equipped with a simple control panel with two modes of operation. The manual mode allows the operator to manually operate the hydraulic unit for servicing. The auto mode enables the pressure switch and drives the hydraulic cylinder in a reciprocating motion. The pump is set-up at a constant speed for the
