Bolted pumps

Designed for critical process applications, the M4 and M8 series consists of 1.5 and 2-in., air-operated, double-diaphragm pumps that can deliver, respectively, up to 70 and 158 gpm and develop up to 125 psig head pressures. The absence of close-fitting parts allows solids to pass through the pump without harm. Abrasive and viscous product is also pumped easily without damaging fluid characteristics. Flow rates and pressures are variable by simply adjusting the air supply pressure/volume or discharge head. Wilden Pump & Engineering Co., Grand Terrace, CA; ph 909/422-1730, fax 909/783-3440.
