Positive Displacement Pump Cutaway


DAC #279 Positive Displacement Pump Cutaway

 DAC #279 Positive Displacement Pump Cutaway, Photo #2

This sectioned, positive-displacement pump allows for convenient classroom or lab training in the operation, construction and maintenance of common metering or "controlled volume" pumps found in industry.

A variety of carefully planned cut way areas and color-coding combine to showcase the internal configuration of the pump. A hand crank is provided allowing for observation of the pump's method of converting rotary motion to reciprocating motion.

All operational components, features, hardware locations and bearings have been retained, allowing for use in maintenance-related training. Most commonly, a Milton Roy, "mRoy" pump is used due to its significant market share and its classic design.

This pump cutaway will make training in pump operation and maintenance more realistic and productive both in the industrial training setting and within technical education programs.
