Gear Materials: PPS (Polyphenylene Sulfide), PEEK (Polyetheretherketone), or Teflon *
Bearing Materials: PPS (Polyphenylene Sulfide), PEEK (Polyetheretherketone), Carbon, or Glass filled Teflon *
O-Rings: Viton, Teflon, EPR (Ethylene Propylene Rubber), Nitrile, or Neoprene *
Ports: 1/8" NPT or 1/4" NPT *
Suction Vacuum: Pumps self prime when wetted with operating fluid to 28.5 Hg" (724mm Hg). Dry lift not recommended. Fluid viscosity, temperature and pressure may affect the performance.
Bypass: Full flow externally adjustable Bypass option available. Adjustment may be performed while pump is operating. The function of the Bypass is to prevent over pressurization of the system as it acts as a relief valve that permits re-circulation of the pumped medium when the Bypass pre-set pressure is reached. The Bypass can prevent motor overload and often eliminates the need for costly external Bypass plumbing and prevents decoupling if differential pressures exceed design limits. Bypass is factory set. Low and high pressure options available.
Operating Temperatures above 140° F (60° C)
In the D Series Product line we offer special sizing option for operating at temperatures above 140° F (60° C). Below is a chart for selecting the option letter for the 17^th position of the model number for specifying your operating temperature.

PPS limit is approximately 250° F (121° C)
Carbon and PEEK limits are approximately 350° F (176° C)
If possible, for temperatures above 250° F (121° C) Carbon bearings should be selected.
