White Knight X Series Pumps

Reliable PTFE and PFA Pumps for High-Purity Chemical Recirculation

X Series pumps are discontinued. Please upgrade to PSA Series or PSR Series pumps. PSA Series pumps provide better performance, improved reliability, shorter lead times, extended pump life, and increased warranty periods. PSR Series pumps are direct replacements. See pump comparison information below.

Overview

X Series pumps are metal-free with PTFE and PFA fluid paths. They distribute chemicals at temperatures up to 100°C (212°F) and allow for air supply pressures up to 4 Bar (60 psi). The pumps perform safely and reliably running continuously throughout their one-year warranty. The pumps are available in two models, X50 and X100, which are capable of maximum flow rates of 20 and 55 lpm, respectively.

Features & Benefits

  • Metal-free PTFE and PFA liquid path
  • Leak-proof, machined design
  • No elastomer O-rings, no leaks, never retorque
  • No lubrication in shift mechanisms
  • No electric motors, which generate heat
  • Pneumatic Logic™ minimizes pulsation and vibration
  • Various liquid connection options
  • Safe, leak-free operation due to no-metal design
  • Polypropylene heads, ceramic in air shuttle valve
  • Minimal parts for durable design
  • Class 100 cleanroom assembly, testing, and packaging
  • Easy to install and service
  • Proven reliable to 200 million+ cycles
  • No preventative maintenance during one-year warranty
