Hydraulic sandwich diaphragm pumps with spring return mechanism Series Exacta Model WS – Seko

  • The new WS series is based on the sandwich principle with double diaphragm which offers considerable advantages, including the presence of a double protection between the pumped and hydraulic fluids and the possibility of selecting the hydraulic fluid, in order to guarantee its compatibility with the half pumped
  • Available in two models: WS1 series: compact and robust and equipped with an aluminum gearbox. The flow rate varies between 0.7 and 111 l / h for a maximum pressure of 60 bar. It is equipped with a stainless steel or plastic head, single or double ball valves and a PTFE diaphragm. Standard connections such as BBPF: AISI, DIN, UNI flange connection on request. The WS2 series has the same characteristics as the WS1 series, but has a flow rate ranging from 1.5 to 500 l / h for a maximum pressure of 80 bar
  • Head: SS 316 L or PVC
  • Flow regulation: by manual, electric 4-20 mA or pneumatic 3-15 psig servomotor
  • Premature failure detector in the membrane – Under normal operating conditions, there is no pressure between the two membranes. In the event of a leak from one of the two membranes, an overpressure is detected
  • Stroke adjustment from 0 to 100% in operation or at rest
  • Lockout device adjustment Electric motors compliant with European standards, multi-voltage and multi-frequency, from 230-400V / 3 50-60Hz
