Through the years, Valmetal has managed to position itself sustainably on the international market through the quality of its equipment combined with the flexibility and efficiency of its customer service.
Valmetal specializes in the designing and the manufacturing of equipment to mechanize and automate most processes for the preparation and distribution of food to farm animals. Valmetal offers two product categories: farm equipment and automated systems.
Valmetal Group’s three brand names Valmetal, Valmetal-Jamesway and Valmetal-US Farm Systems, have been merged under the single brand, Valmetal.
About the Solution:
Solid-Trans Manure Piston Pump
The Solid-Trans is capable of transferring solid or semi-solid bedded manure long distances with low power requirements. The 7.5HP hydraulic power unit makes the Solid-Trans an excellent choice for use with single phase electricity or anywhere that power availability may be limited.
The Solid-Trans pump is equipped with a 5” hydraulic cylinder and a heavy gauge 20” diameter stainless steel pumping cylinder. The Solid-Trans has a 20” inlet and a 16” diameter outlet, and the pumping chamber is equipped with heavy guillotine doors. Manure is drawn into the pump chamber during the upstroke and pushed out during the downstroke. The guillotines act as check valves so that manure may only flow toward the storage.
Solid-Trans pumps are mounted in a dry pit and are equipped with a hopper inlet. The output is 16” diameter SDR26 PVC pipe. Steel 16” pipe is also available.
Solid-Trans pumps are intended for use in manure with long or short bedding. The Solid-Trans may not be used with sand bedding. Depending on the amount and type of bedding used, it is often necessary to add some water into the hopper or the manure gutter while the pump is running. This water helps material slide into the inlet pipe and maintains a suction seal in the inlet.
Semi-Trans Manure Piston Pump
The Sand Specialist
The Semi-Trans is capable of transferring semi-solid manure long distances with low power requirements. The 7.5HP hydraulic power unit makes the Semi-Trans an excellent choice for use with single phase electricity or anywhere that power availability may be limited.
The Semi-Trans pump is equipped with a 5” hydraulic cylinder and a heavy gauge 20” diameter stainless steel pumping cylinder. The Semi-Trans has a 16” inlet and a 16” diameter outlet, and the pumping chamber is equipped with heavy steel flapper doors. Manure is drawn into the pump chamber during the upstroke and pushed out during the downstroke. The flappers act as check valves so that manure may only flow toward the storage.
Semi-Trans pumps are always mounted in a dry pit. This may be beside a reception pit with a suction tube through the wall, or the pump can be equipped with a hopper inlet for use with cross-gutter cleaners. Depending on the type of manure and the distance to the storage, the output is either 16” or 12” diameter SDR 26 PVC pipe. Steel 16” pipe is also available.
Semi-Trans pumps are intended for use in semi-solid manure with no long bedding. Short bedding or sand bedding are acceptable. When using sand bedding it is important that no water be added to dilute the manure. A high water content will cause sand to settle in the transfer pipe and rapidly block the pipe. Higher water content is acceptable with organic bedding.
Air Risers may be installed along the length of the pipe. This kit includes a 6” diameter pipe that is attached in a Y-joint to the manure pipe and runs vertically to end above ground level. Compressed air may then be used to rapidly push manure forward and scour the pipe clean. This is a normal maintenance with sand bedding. Air risers are also recommended with organic bedding on systems with a long pipe to allow easy access in case of line plugging.
Liqui-Trans Piston Manure Pump
The Liqui-Trans is capable of transferring liquid manure very long distances with low power requirements. The hydraulic power unit is available in 5HP or 7.5HP models, which makes the Liqui-Trans an excellent choice for use with single phase electricity or anywhere that power availability may be limited.
There are two models of Liqui-Trans pump available: Standard Duty is equipped with a 3” diameter hydraulic cylinder and the Heavy Duty, which is equipped with a 4” hydraulic cylinder. Both models use a heavy gauge 20” diameter stainless steel pumping cylinder and urethane-edged flapper doors.
Liqui-Trans pumps may be mounted in a dry pit beside a reception pit with a suction tube through the wall, or at floor level with a suction downspout extending down into the reception pit. Depending on the distance to the storage, the output is either 6” or 8” diameter PVC pipe. This small diameter pipe makes installation very economical.
Liqui-Trans pumps are intended for use only in very liquid manure (maximum 10% solids) with no long bedding. Manure in the reception pit may be preconditioned to meet these requirements by adding waste water and/or by homogenizing if required. The Jamesway Electric Prop Agitator is commonly used with the Liqui-Trans to precondition the manure.
Sand bedding is not recommended with the Liqui-Trans system. The high water content required in the manure will cause sand to settle in the transfer pipe and rapidly block the pipe. The exception is when the Liqui-Trans is used to lift material into a separator system. A Jamesway representative will review your plan and recommend a self-cleaning pipe configuration for these systems.
Air Risers may be installed along the length of the pipe. This kit includes a 6” diameter pipe that is attached in a Y-joint to the manure pipe and runs vertically to end above ground level. Compressed air may then be used to rapidly push manure forward and scour the pipe clean. Air risers are recommended with on any system with a long pipe to allow easy access in case of line plugging.
Please contact Jamesway for review and recommendations for systems exceeding 1000 feet of pipe, or systems with extreme vertical lift.
Mechanical Piston Pump
With 40 years of experience in the field, Jamesway Mechanical Piston pumps are famous for their reliability and long life. These simple manure pumps require only minimal maintenance and yet will provide many years of trouble-free performance. The Mechanical Piston pumps are designed to transfer manure from the barn to storage at very high throughput, making these the pumps of choice when capacity is critical.
Solid manure or semi-solid manure with long bedding (max 1 bale per 10 cows) should only be used with the 10 x 14 base unit. This pump discharges through 15” diameter PVC pipe, and the maximum distance will vary from 80 to 150 ft with a 10HP motor, depending on the manure consistency. Some additional water is always required to help manure flow into the hopper.
Slurry or liquid manure can be pumped with either base unit but the smaller 10 x 10 model is usually preferred because it is able to pump longer distances. This unit uses 12” diameter PVC pipe and can pump up to 200 ft with a 10HP motor. Either base unit may also be equipped with 7.5 or 15HP motors for shorter or longer pipe lengths. Your Jamesway Dealer will help select the correct model for your needs.
The pumping cylinder and piston are the guts of the machine. On the downstroke, the piston pushes manure through the cylinder and past a flapper door. On the upstroke, manure passes through the hollow piston. The front of the piston is a flapper door, and as the piston begins the next downstroke, the flapper closes and pushes the manure ahead of it. While the base unit is permanently installed in concrete, all working parts are easily removable for future service or replacement. It will take many years to wear these parts out but when you need to replace them, an inexpensive ReNew Kit makes your pump brand new again.
Solution Strengths, Weaknesses and Critical Indicators
NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.
General Support & Other:
- Can be an integral part of many manure management systems
- Most projects have at least some equipment that supports operations of the main technology
- This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.
Newtrient will continue to work with Valmetal to further refine the cost and performance information as more information becomes available and as new commercial dairy installations come on line.
