Multiquip MP200SDLTE, MP200DLTE General Information, Impeller, Wear Plate, Priming System, Volute

The Multiquip Dry Prime pump is a prime dry and prime- assist pump that can handle dewatering, sewer bypass, and wellpoint applications.

The Dry Prime pump uses a vacuum pump to remove the air. This becomes important in certain applications such as long suction hose runs or multiple suction points (such as wellpoints). In these cases, high volumes of air enters into the pump. Dry Prime uses direct-drive vacuum pump to efficiently remove very large volumes of air quickly to obtain the priming necessary for these special applications. Dry Prime is very useful when you have to move a lot of water fast.

Impeller

The Dry Prime impeller has a patented design to eliminate cavitation. It is a 2-blade spiral, smooth flow, open, non-clog impeller, designed to handle up to 3.2-inch solids.The impeller pulls water directly into the pump from the priming tank, reducing friction losses, and then pushes it out the volute discharge. This design does not cause turbulence normally found in centrifugal pumps.

Wear Plate

In conjunction with the impeller, the wear plate gives a perfect match for great pump performance and durability. The wear plate can be fully adjusted up to .6 inch (15mm) for wear.

Priming System

The vacuum system is innovative, simple, yet rugged and dependable. I uses direct drive which means no belt failure and with only one moving part, means no maintenance. It uses liquid-ring design with a closed water system. Separate oil bath lubrication for the seal and bearings with oil reservoir, can run dry without damage. It operates quietly with no pollution or unwanted discharge noise.

GENERAL INFORMATION

Float and Backflush (Priming Tank)

The priming tank float is a one-piece welded construction, rubber valve seat, self-aligning rubber hinge. This design increases reliability. The backflush valve allows for cleaning of the suction strainer or wellpoint headswhile the engine is running.

Fuel Tank Frame and Trackbar System

Run time is up to 72 hours with the Dry Prime’s fuel tank, good for continuous running for those long-term jobs.There are two corner fuel drains to check condition of fuel. The TrackBar system allows for the easy addition of jack stands, fenders, axle, lifting bail, and other options. This allows for fast and easy positioning of the jack stands on the job site to fit the application, or to add subtract jack stands as required.The removable, retractable towing tongue minimizes storage requirements.

Volute

The pump volute has an external inspection cover to inspect or clear the impeller. The pump shaft bearings and mechanical seal are run in independent oil baths for low maintenance.

LOFA Engine Control Panel

Vandal protected panel that provides engine status and shut- downs in the event of low oil pressure, high engine heat, and alternator belt breakage. Optional auto-start module with floats can be added for automatic start-stop of pump engine and pumping operation.
