  • Wilden pumps and accessories are employed in a host of difficult fluid transfer applications ranging from circulation duty in cleanroom environments to municipal sludge pumping.
  • The Wilden pump is shear sensitive and keeps foaming to a minimum by utilising two pumping chambers which reduce velocity within the pump.
  • 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.
  • The pump can run dry, self-prime, and 'deadhead' without damage in a wide variety of process and waste applications.
  • Flow rates and pressures are varied by simply adjusting the air supply pressure, air volume, and / or discharge head.
  • With no packing or leak-prone dynamic seals, Wilden can transfer hazardous liquids with ease.
  • Air operation makes the Wilden pump intrinsically safe by design.
