Frequently Asked Questions
Does the C98 include a motor and receiver tank?
No. This is a bare pump replacement assembly, not a complete compressor. Your motor, tank, belts, guard, controls and associated components must be supplied separately.
What horsepower is the FMLC98 designed for?
FS-Curtis lists 20-30 HP for this model. Confirm existing equipment, pump speed and installation requirements before ordering.
Is this single-stage or two-stage?
The C98 is a two-stage oil-lubricated reciprocating compressor pump. It is intended for compatible industrial compressed-air applications.
What is the maximum working pressure and duty cycle?
FS-Curtis specifies 250 PSI maximum pump pressure and 70% maximum loaded duty cycle. The completed compressor's operating settings must respect the ratings of every component.
What RPM and flywheel arrangement does it use?
The manufacturer specifies 500-950 RPM and a 4B flywheel configuration. Confirm the motor and pulley arrangement before installation.
What discharge connection does the pump have?
The published discharge size is 2 in. NPT. Verify pipe compatibility and the complete system's pressure rating.
Does the bare pump ship with lubricant?
No. It ships without oil and has a nominal 6-quart capacity. Use the appropriate manufacturer-approved compressor lubricant prior to startup.
How do I choose the correct replacement pump?
Compare your existing pump number, horsepower, RPM, flywheel, mounting, and air connections. Compressed Air Advisors can help confirm compatibility before ordering.
