Valmetal Manure Pumps

Manure pumps are essential components on dairy farms, used to transfer liquid manure from storage pits or lagoons to other locations for land application or further processing. The specific design and operation of manure pumps can vary.

Mid Valley Manufacturing offers three types of dairy barn manure pumps including:

Valmetal Vertical Electric Agitator Pumps

Valmetal 12”-16” Vertical Electric Pumps

Valmetal Semi-Trans Manure Piston Pumps

Vertical Electric Agitator Pumps

A vertical electric agitator pump is a type of pump commonly used on dairy farms for agitation and pumping of liquid manure stored in pits or lagoons. The primary purpose of the agitator is to prevent the solid components of manure from settling at the bottom of storage facilities, ensuring a more uniform consistency for pumping and application.

A vertical electric agitator pump consists of a vertical shaft with an agitator mechanism attached to the lower end. The pump is usually mounted vertically in the manure storage pit or lagoon and operated by a control panel.

The agitator on a vertical electric agitator pump is designed to stir and mix the liquid manure, preventing the accumulation of solids at the bottom of the storage structure. Common agitator designs include propeller agitators or similar stirring mechanisms.

The vertical design ensures efficient mixing and agitation throughout the storage volume. The agitator is typically activated intermittently or continuously, depending on the dairy farm’s management practices. Regular agitation is essential to maintain a homogeneous mixture, making it easier to pump and ensuring that nutrient distribution is consistent when the liquid manure is applied to fields.

Vertical electric agitator pumps are integral to the manure management process on dairy farms, contributing to the prevention of solids settling, improving pumpability, and facilitating the efficient use of liquid manure as a valuable nutrient resource for crops.

Manure Piston Pumps

Piston pumps are positive displacement pumps, meaning they move a fixed amount of fluid (in this case, manure) for each cycle of operation. They are commonly used for handling viscous or thick substances, making them suitable for applications where manure may have a higher solid content.

A piston pump typically consists of a cylinder, a piston, inlet and outlet valves, and a power source. The inlet and outlet valves control the flow of manure. The inlet valve allows manure to enter the cylinder, and the outlet valve directs the pumped manure to the desired location.

In operation, the piston moves back and forth within the cylinder. During the suction stroke, the piston moves away from the inlet valve, creating a vacuum that draws manure into the cylinder. In the discharge stroke, the piston moves toward the outlet valve, pressurizing the manure and forcing it out through the outlet.

Piston pumps are effective for pumping manure with varying viscosities and solid contents. They can handle a wide range of materials, including thicker slurry. The positive displacement nature of piston pumps contributes to consistent pumping rates.

The flow rate of the pump can often be adjusted to meet the specific requirements of manure management on the farm. This adjustability is valuable when different application rates are needed for land spreading.

The pumped manure can be directed to fields for nutrient application or to storage tanks for further processing. The piston pump contributes to the efficient transfer of manure from storage to application sites.
