Hale SMR - Manual (Page 21)

Stainless Max Series Pumps 2-7
Introduction
Hale offers a variety of pump
gear ratios to accommodate a
wide range of end-user and
apparatus manufacturer
requirements based on the
pump's intended use, horse-
power and speed rating of the
engine, and the torque rating
of the transmission PTO.
Also see subheading “X Series
Gearbox” on page 2-8 for
additional information about
the gearbox.
Pedestal - SMR Series
SMR series pump shafts run
through a bearing housing
that acts as a mounting
pedestal. See Figure 2-8 for
a sample configuration.
This pedestal is constructed
of fine grain cast iron, and
consists of bearings and a
shaft. Additionally the SMR-
A pump is driven through a
26 ear helical gear box.
PUMP DRIVES
There are four common SM pump drives used on fire fighting
apparatus:
❑
Operation from the truck chassis drive shaft (split-shaft gearbox).
❑
Operation from a separate engine.
❑
Operation from the front of the truck chassis engine (front engine
PTO) crankshaft.
❑
Operation from a PTO from the truck transmission, a PTO before
the engine drive transmission or a PTO from the four-wheel drive
transfer case.
Hale SM pumps are built to produce the volumes and pressures shown
on their respective performance curves.
