Self Priming Trash Pump

Designed for economical, trouble-free operation, the superior solids-handling capabilities of the TSP Series Self-priming pumps make them ideally suited for a variety of applications including solids-laden liquids and slurries. The large volute design allows automatic repriming in a completely open system without the need for suction or discharge check valves.

Available in discharge sizes of three, four, six, eight and twelve inches, this line of self-priming pumps boasts capacities to 5285 gallons per minute (333.3 liters per second) and heads to 131 feet (40 meters). Pumps four inches and larger are engineered to allow up to three-inch diameter spherical solids to pass through any critical area, including the recirculation port.

TSP Series Self-priming pumps are available in several configurations, including a B version for higher head applications, close-coupled or engine-driven models. All eu-flo‘s TSP Series pumps are backed by a five-year manufacturer’s warranty.

Remove Solids Management System

The remove system features an aggressive self-cleaning wear plate incorporating a number of notches and grooves, as well as a patent-pending lacerating tooth, that helps break up stringy materials and pass them through the pump without impacting performance or interrupting service. A special back cover includes a patented lightweight inspection cover that can easily be removed if it is necessary to inspect the impeller. The innovative design greatly reduces troublesome clogging and expensive downtime.

TSP Trash Pump, pedestal and frame mount. Self priming centrifugal solids handling pumps designed for Municipal and Industrial applications. Frame mounted pump, no base or motor. For economical, trouble-free operation in handling solids-laden liquids and slurries. Performance will vary with pump speed, see performance curves. Values given are for maximum at 1750RPM.

The combination of different sized pumps, impeller trims and speed variations ensure that the correct capacity pump will be matched to the exact requirements of your system, whether it’s a small sub-division or a large waste collection system. These pumps feature a large volute design that allows them to reprime automatically in a completely open system without the need for suction or discharge check valves – and they can do it with the pump casing only partially filled with liquid and a completely dry suction line.

Base plates, motors and coupling guards are all available as options. See performance chart for flow and head at various RPM and impeller diameters.

High Performance Balanced Pump

High Performance Balanced Pump
High Performance Balanced Pump

Higher Performanced Self-balancing horizontal multi-stage centrifugal pump impeller adopts a back-to-back arrangement to substantially eliminate the axial force, and the residual axial force is bear by a pair of back-to-back angular groove ball bearings. Because there is no balance device, that is, eight the disc friction loss no balance return loss, the pump efficiency is increased by 5-1% compared with the multi-stage pump of the same category, and the various failures of the pump caused by the failure of the balance device are completely solved. Greatly extend the life of the pump:

High-performance sealing, mark: traditional mining multi-stage pumps are filled with packing. The advantages of packing sealing can resist solid medium, but there are leakage problems in the use of engineering, mechanical seals are leak-free, but used in medium with solids. The service life is very short. our new developed mining multistage pump produced The seal used is a high-performance seal that combines the advantages of a packing seal and a mechanical seal in a medium with solids.

Long-term use without leakage, this seal is a new type of patented high-performance seal resistant to solid medium and developed by our company.

The bearing housing never enters the water. This technology is a newly developed patented technology by our company, which ensures that the pump is in use and in a static state without liquid entering the bearing housing. This further extends the bearing service life of and reduces the user’s Maintenance costs.

Coating Improving Efficiency&Performance

Efficiency&Performance Improvement Program for New & Existing Pumps up to 3-5% on new pumps, and up to 8% on those already in service. Improve value addition by Repair & Protection thus Extending Service Life of Pumps.

The need to improve operational efficiency & performance of Pumps: The pumps are the heart of any system that handles fluids – the second most common piece of machinery used in general industry. Pumps use mechanical forces to move fluids namely gases, liquids, or slurries from one location to another what is referred to as a hydraulic passage. The hydraulic passage is the trajectory followed by the fluid inside a pump, and it depends on the design of each pump.

The transfer of fluids accounts for the largest single use of energy worldwide with millions of litres pumped from one location to another every second of everyday worldwide, it is therefore understandable that the rising cost of energy has lead to all energy intensive Industries such as Cement, Sugar, Steel, Textile, Fertilizer, Paper & Pulp, Refinery, Aluminium, Petrochemical etc., to look for solutions to improve operational efficiency of Pumps.

A major problem is increased turbulence caused by the detrimental effects of erosion & corrosion. This leads to rough and pitted surfaces which in turn, increase drag, therefore reducing the efficiency of the system. In fluid dynamics, water molecules on the pump surfaces are stationary. Discrete water molecules in the flow behave as separate entities creating vortices and cross-currents which result in energy losses in addition to those arising from skin friction, which still continues to be exerted next to the boundary layer, in a thin film known as the laminar sublayer.

The energy cost of a pump represents the largest portion of its lifetime costs – much more than the capital cost. In fact, operating costs can represent as much as 95% of the overall lifetime costs of the pump. Therefore, an improvement in energy efficiency will represent a significant reduction in lifetime costs. Deterioration in service can reduce efficiency, leading to as much as 10-15% extra energy consumption.

The Devcon’s 111760 Brushable Ceramic Solutions

DEVCON ‘s high performance BRUSHABLE CERAMIC 11770&11760

Reclamation Putties are used for the repair and maintenance of pumps in the form of rebuilding compounds with the ability to rebuild corroded components back to OEM’s original specifications and 11770&11760 in-situ coatings offers low friction surface that protect the substrate against damage from corrosion, abrasion, and chemical attack by producing renewable working surface, protecting the structural integrity of the original substrate at much lower costs compared to replacement. The coating’s hydrophobic nature makes the water simply roll off the surface and wear by abrasion is minimized by its encapsulated blend of lubricating agents and abrasion resistant fillers. Moreover, the pump is rebuilt and returned to service within a few days, saving the client from many weeks wait for a new replacement pump.

Devcon’s corrosion and erosion resistant material – it is possible to not only restore flow rates, but also increase the efficiency level to beyond that when it was newly installed due to low surface tension. The material allows an ultra smooth surface that reduces turbulent flow, thereby increasing efficiency. The smoothness on the surface of this type of coating (Gap Fill 0.0625″-0.0725″) is 20 times greater than polished stainless steel (Ra 1.19um). Also, being a solventfree coating, health and safety risks are reduced during application and is recommended for contact with potable water.

The resultant reductions in power consumption result in typical returns on investment from 3 months to 6 months depending on the size of the pumps. Even the refurbishment of pump components that once would have been considered ‘scrap’ can be realized. It will increase the efficiency of a pump over its “as new” condition giving a rapid payback in reduced energy costs. When applied to fluid flow equipment, this type of coating has been proven to improve hydrodynamic performance by increasing overall efficiency through reducing power consumption, increasing fluid flow rate or pressure.
