Description

The MVP IV Pump System includes:
- MVP IV Pump
- Well Clincher (well cap)
- Air Particulate Filter Regulator

The MVP IV Pump uses an internal float that responds to the fluid level within the pump body, automatically cycling the pump. As the pump fills with fluid, the float moves to the upper position activating the mechanical arm which opens the air inlet valve. The air enters the pump chamber, simultaneously pressurizing the vessel and closing the upper and lower fluid inlet check valves. The air pressure pushes the fluid through the 3/4 in. (19 mm) discharge line to the surface. As the fluid is emptied from the vessel, the float returns to the lower limit position simultaneously closing the air inlet and opening the air exhaust valve. The volume of air used to move the fluid is then exhausted either in the well or through the well clincher at the surface. This cycle is automatically repeated depending on the recharge rate of the fluid being pumped.

Mechanical advantage is provided as the air inlet and air exhaust valves are incorporated on the same side of the pump. This provides seven times the mechanical leverage that would be available with the valves located on opposite sides of the pump head. This results in a positive valve shift, eliminating pump stalling. Also, it permits the use of larger, simpler air and exhaust valves which eliminate air quality concerns.

An Override Feature in the MVP IV pump allows it to be cycled from the surface. This can be used to empty the pump and hoses prior to removing them from the well and is especially convenient when removing the pump from deep well installations. An additional 1/4 in. air line is required.

Stainless Steel Pump Body - is standard and offers superior chemical resistance and durability.

Fiberglass Body - Optional, a fiberglass body can be substituted to reduce the overall weight of the pump.

Syntactic Float - Standard, The syntactic float material combines an epoxy with a micro bubble glass resin to provide a durable material that is chemically compatible with the types of fluids encountered in most applications.

Stainless Steel Float - Optional, when the MVP IV pump is used in field conditions that require an all stainless steel pump for chemical compatibility.

Short Pump Lengths - Depending on your specific site requirements, the MVP IV pump can be can be shortened up to 5 inches to allow for shallow water conditions. The bottom loading MVP IV pumps can achieve a minimum draw down of 18 inches by installing a stop fitting on the control rod.

Shallow Water Pump - The pump body and internal mechanisms are customized to allow the pump to be used to maintain a total fluid draw down in shallow wells with as little as 11.5 to 14 inches of water*.

Complete access to all the internal components of the pump is provided with the thread-together design. The pump head can be easily removed should access to the air inlet and exhaust valves be needed.

Loading Configurations

The MVP IV pump design allows the loading configurations to be easily changed to match site requirements. The top inlet port is machined into the head of every MVP IV pump, and two bottom assemblies - a solid bottom or a bottom inlet assembly - can be used to achieve the desired pump configuration.
