FOOTNOTES:
1 Current P-Series pumps have Universal ANSI/DIN Flanges (Code U). P-Series pumps manufactured in or before May 2021 may
have distinct ANSI (Code L) or DIN (Code E) Flanges. (See P-Series Model Coding, Position 2 on page 5.)
2 Based on average test data with water at room temperature and maximum pump speed of 1750 RPM.
3 Based on pressure rating of Flanges at ambient temperature. Above 100°F to 200°F, derate pressure by 0.35 PSI/°F.
4 Pump may require trimmed gears depending on the material and temperature. Consult factory.
5 Dry Suction Lift is specified at Maximum Speed with PEEK Gears and Carbon Bearings. For other materials, priming of the suction
line is required to prevent wear and possible damage to internal components.
6 Approximate weight of pump, excluding motor.
7 Obsolete Alloy-C/PFA-Lined Containment Can is available only for Replacement Cartridges in existing pumps.
8 Includes Retaining Rings for Gears and Inner Magnet.
9 Kalrez Grade 1050LF or Chemraz 555 is optional for special applications.
NOTES:
1 The actual maximum surface temperature depends not on the pump but primarily on the temperature of the fluid being pumped.
Pump surfaces will be approximately 20F (11C) above the temperature of the process fluid.
2 The operating ambient temperature range depends not on the pump but on the motor, which is a function of motor design,
enclosure, insulation class, loading, ventilation and other factors. Refer to motor manufacturer's specifications.
