Caution!
Following operating conditions can cause early damage of the pump by spring breakage:
• dirty, wet or contaminated air supply
• too small suction pipe diameter or too large particles in the pumped liquid
• blocked valve seats or viscosity of the liquid exceeding 0.000 mPas
• high flow rate at a back pressure of more than ∆ p = .4 bar
• safe operating pressure exceeded
Caution!
Following conditions cut down the continuous operation of the pump:
• high stroke frequency
• Flow rate at maximum value
• resistance at suction side (large suction head, filter or valve)
• viscous liquid
• high operating pressure
• During continuous operation (t > h/day) operating pressure and flow rate must not exceed more than the
half of the maximum admissible operating pressure respectively the maximum possible flow rate.
• high suction prepressure
These operating conditions and long running times can wear movable parts after 3-6 months.
