Ramparts Diaphragm Pumps The rugged construction of the Ramparts Diaphragm Pumps stand up to
the abuses of the most demanding sludge and slurry applications, and they overcome the
'high-wear' problems commonly found in air driven diaphragm and progressive cavity pumps.
The Air Driven Diaphragm Pump is capable of operating dry,
on suction lifts of up to 20 feet, and handling high solids content (to approximately
70%). Depending on pump model, they will pass up to 3" diameter solids!
Pump stroke rate, discharge stroke time, suction drive
pressure, and discharge drive pressure can all be adjusted independently. Pumps will
easily handle the heaviest sludges at their rate of accumulation in clarifiers and
settling basins.
The Ramparts diaphragm pump operate simply: compressed air
applied to the top forces the diaphragm down, discharging liquid; the solenoid is then
signaled by an adjustable controller to halt incoming air; compressed air is directed into
the bottom of the air cylinder, raising the air cylinder piston and retracting the
diaphragm, filling the pump cavity for the next stroke; used air is exhausted to the
atmosphere; and the cycle repeats.
Ramparts Air Driven Diaphragm Pump Benefits:
- Less air required compared to spring versions
- Lower vertical height
- Quiet operation
- 20' suction lift capability
- Less maintenance and down time
- Simply and easy maintenance
- Easy access to check valves... no tools required
- A total of only 3 moving parts
- Virtual elimination of muffler icing
- Handles larger solids

Ramparts Centrifugal Pumps Ramparts Pro-Flo Elastomer Lined End-Suction Centrifugal
Pumps are specialized for abrasive/corrosive applications, offering outstanding
resistance to a wide range of chemicals and corrosives, both acid and alkali. And they
feature a unique hydraulic design incorporating tangential discharge which guarantees
continuous pumping performance and efficiency. Pump, base, and guard are epoxy coated for
external protection. Pumps are capable of handling up to 1" spherical solids,
depending on pump size. Pumps are available in four sizes, 2x1-1/2x8-1/2, 3x2x10-3/4,
4x3x11-1/2, and 6x4x12.
Ramparts AVS Pro-Flo PVDF Kynar Lined End-Suction
Centrifugal Pumps are specialized for highly corrosive services. Inside, the
Kynar lining has outstanding resistance to acids, alkalis, and many solvents... even at
elevated temperatures. Outside, a special double epoxy coated, cast iron guards the pump
exterior.Pump accepts single or double mechanical seals, or packed box. Pumps are
available in two sizes, 1-1/2x1x6 and 3x1-1/2x6. |
