Operating Parameters
** For all pump sizes with O-ring seals, the maximum product pressure is 100 psi (7 bar).
Other inlet/outlet sizes are available. Contact SPX FLOW Application Engineering.
Pump max temperature is 300°F (149°C).
Operating temperatures depend on the rotor style used. See the rotor descriptions below.
* Contact SPX FLOW Application Engineering for higher pressures or higher temperature applications.
Operating the pump outside the stated operating parameters may result in severe personal injury or death.
"Low Viscosity" rotors may be used with liquid temperatures up to 180°F (82°C).
Between 160° (71°C) and 200°F (93°C), consider other application factors, such as; speed of operation,
differential pressure, lubricating properties of liquid being pumped, and product viscosity. If these factors trend
toward a difficult application (high speed, high pressure, non-lubricating) then "Standard" clearance rotors are
recommended.
"Standard" clearance rotors are recommended for use with liquid temperatures between -40°F (-40°C) and
300°F (149°C). They provide additional clearance in the front face area plus rotor to body areas. Because of
this additional clearance there is more slip (inefficiency) with low viscosity liquids, which the pump must
overcome with higher operating speed (rpm.) VHP (viscous horsepower) is slightly lower when using standard
clearance rotors. Standard clearance rotors are also used when the product viscosity is above 200 CPS.
"316SS" clearance rotors are made from 316 stainless steel material (in place of standard non-galling alloy
88) and recommended for use at temperatures up to 200°F (93°C). These rotors provide additional clearance
all around (more than Standard clearance alloy 88 rotors) to ensure no running contact between the 316 SS
rotors and other 316 SS pump components. Because of this additional clearance, there is more slip
(inefficiency) with low viscosity liquids, which the pump must overcome with higher operating speed (rpm).
VHP (viscous horsepower) is slightly lower when using "316SS" clearance rotors.
NOTE: Consult SPX FLOW Technical Services for applications near 300°F (149°C) or above 200°F (93°C)
with 316SS rotors. For clearance data, see Table 18, “Rotor Clearances,” on page 91.
