“D” refers to Distance Piece, a section inserted between the air drive and the hydraulic body to separate them at a distance greater than the travel (Stroke) of the plunger/piston.
The distance piece is vented so that any leakage from the fluid end will not be able to contaminate the air drive and vice versa.
Many times, the fluid pumped is not compatible with the air drive O-Rings, and cause swelling which could result in higher levels of friction and can stop the pump.
When critical fluids are used, it also protects the hydraulic section from air drive contaminants such as oil or moisture.
The distance piece is also used when the fluids pumped are at a temperature that could adversely affect the air drive seals. It provides a distance for heat transfer to minimise the temperature differential.
