Operating Procedures
Tractor Selection
Power
The Diaphragm Pump requires a 20 HP minimum. Your tractor should have 25-30 horsepower available on the PTO
shaft. It also needs to have the ability to stop the TR500PHS, when full of water. A small tractor is more maneuverable in
a poultry house. We recommend using a tractor with a 45-60 HP available on the PTO.
PTO
The diaphragm pump is designed to operate at a 540 RPM speed. Tractors come standard with a maximum PTO
speed of either 540 or 1000 RPM.
The shape of the PTO shaft usually indicates the PTO speed.
Small tractors (80 HP or less) generally come standard with 540 RPM PTO (1-3/8” shaft with six splines).
Large tractors (80 HP or more) generally come stock with 1000 RPM PTO (1-3/8” 21 splines or 1-3/4” 20 splines).
WARNING! Do not try to operate your TR500PHS with a 1000 RPM PTO!
