The Motorized Diaphragm Pump (MDP) pumps water, brine, mud, sewage, petroleum products and many chemicals. This versatile pump comes in several models: HP700EF, HP700G, and the HP700DC. They are low maintenance units. Electric models are 1-HP, specify: 1 Phase, 3 Phase or 12 volt DC direct.

FEATURES

Self-priming MDPs can run dry without damage to the pump seal.

The natural rubber compound diaphragm is strong and long lasting.

Easy to replace valves.

Steel base for secure mounting.

HP700 E & G units are equipped with a carrying bar.

Units range from 26-32 GPM.

INSTALLATION & OPERATION

Determine pump location and, if desired, secure in place (5/16″ bolts recommended).
Connect suction hose or pipe to suction flange.
If desired, connect discharge hose or pipe.
Connect power source (electric models).
Start pump; may be operated indefinitely.

SAFETY & RECOMMENDATIONS

To extend diaphragm and valve life, flush the pump with water after each use.
If pumping liquid other than water, flush thoroughly with water after use.
Replace the diaphragm and valves that show signs of wear, cracking or corrosion.
For AC models: make sure electrical connection is properly grounded.
Keep clear of rotating and reciprocating components.
