Hale MG - Manual (Page 32)

Muscle Pumps
1-25
These valves can be used in either suction or
discharge lines.
Each discharge valve on a Hale pump may be
equipped with a drain. Opening the drain before
uncoupling the hose relieves the pressure in the
line. Also, water must be drained from the pump
during freezing conditions through the main drain
valve.
Tank Suction Valves
There are two different Hale valves that can be
used as tank suction.
The first valve is the Hale 30BPF, this valve is an
integral flanged valve that mounts to the 8-bolt
flange pattern at the tank suction port of the
midship pump. The valve is a lever operated 3-inch
full flow ball valve and can be connected to the
tank using a 4-inch Victualic™ coupling or 3 inch
NPT pipefitting or a 4 inch hose.
Another option for the tank suction valve, is the
40BDS Model valve. The 40BDS valve is a 4-inch
full flow ball valve that is available lever operated
or can be equipped with an electric motor gear
operator. The nature of the 40BDS permits
mounting to the tank suction opening on the pump
using an 8-bolt 3.5° angled flange or an 8-bolt
straight flange. Tank connection is by use of 4 inch
NPT threaded pipe fittings or 4 inch or 5 inch
Victualic™ clamps.
The 30BPF and 40BDS valves are provided with an
optional check valve flapper to prevent pressurization
of the water tank.
In-line Valves
Hale has several types, sizes, manual, and
electrically operated in-line valves. The BP series-
bronze valves range in size from one inch to three
inch in half-inch increments.
