DESCRIPTION
The MEGA Mobile Pump (MMP4) is a towable water
lifting station. The MMP4 may be towed by a vehicle
capable of at least a 6,000 pound (2,725 kg) towing
capacity, 1,000 pound (450 kg) tongue weight, and
equipped with the appropriate weight rated Class IV
trailer hitch with a 2 5/16 inch ball. The MMP4 can be
transported to a water holding pond and be set up
by one individual.
The MMP4 is a self-contained pumping station fitted
with a hydraulically driven 12 inch axial water pump
that has the potential to lift water 25 feet (7.6 meters)
from pump level to fill water distribution equipment
(maximum height: 17 feet or 5.2 meters above
ground level).
MMP4s are equipped with: hydraulically lifted inlet
and discharge booms with safety retaining chains
and travel locking devices, DOT rated lighting, 16
inch load range 'E' on-highway trailer tires, a fold
away hitch with safety chains, a vacuum break with
an anti-siphon discharge sock on the discharge
boom, 23 gallon (87 liter) hydraulic oil tank filled with
Chevron Clarity AW 46 hydraulic oil, a gear type
hydraulic pump driven by a Caterpillar C2.2T series
diesel engine, and a 50 gallon (190 liter) capacity
diesel fuel tank equipped with shut off valves.
The MMP4 needs a minimum of 2.5 feet (0.76 meters)
of water above the inlet of the water pump for proper
operation.
