Drive Pump to be connected to prime mover by means of a flexible coupling that is aligned
to a maximum of .006” (.152mm) total indicator reading. No overhung or side loads
permitted. Alignments greater than .006” indicator reading could cause increased
noise and vibration as well as premature shaft seal wear resulting in leakage.
Fluid recommendations A premium quality hydraulic oil with anti-wear additives is recommended, but not
required. Refer to publication S-106 “Petroleum Hydraulic Fluids” for a list of fluids
which meet or exceed the necessary lubrication requirements. Consult factory for
use with water base fire resistant fluids.
Minimum 100 SUS (21 cSt)
Fluid viscosity at Maximum 1000 SUS (216 cSt)
operating temperature Optimum 150-250 SUS (32-54 cSt)
Maximum start-up 4000 SUS (864 cSt)
Fluid temperature Normal inlet fluid temperature should not exceed 140°F (60° C). Always select a fluid
for optimum viscosity at operating temperature. Consult factory for applications assis-
tance when inlet fluid temperatures over 140° F (60° C) are expected.
Seals Fluorocarbon Standard
Filtration Fluid cleanliness per ISO/DIS 4406 should be 18/15 or better for pressures of 2000 psi or
less. For continuous operating pressures of 2000 to 3000 psi, fluid cleanliness should be
17/13 or better.
