P Series Air Driven Diaphragm Pumps
They overcome the "high-wear" problem commonly associated with double diaphragm and progressive cavity pumps. Ramparts ADD pumps are capable of operating dry, on suction lifts up to 20 feet (6.5 m) and handling high solids concentrations of up to 70 per cent.
Precise controls allow pump stroke rate, discharge stroke time, suction drive pressure and discharge drive pressure can all be adjusted independently. Pumps will easily handle heavy sludges at their rate of accumulation in clarifiers and settling tanks.
They are also an excellent choice for filter press feed systems where specialist “pressure ramp-up” controls ramp discharge pressure independently and progressively to equalise pressures either side of the diaphragm to extend diaphragm and valve life and minimise downtime and costs.
