PUMP MATE
PRE-PRESSURIZED DIAPHRAGM OPERATION
5-YEAR LIMITED WARRANTY
State Industries Pump Mate tanks are designed for installation flexibility and years of trouble-free service. Smooth,
dependable diaphragm design and operation provides precise
control of system operation cycles. Free-standing and in-line
vertical tanks are available, as well as horizontal tanks with
universal pump mounting bracket. Every State Pump Mate
tank is made in the U.S.A.
Higher Drawdown Than
Competition!
Convenient Air Charge Valve.
Butyl Diaphragm ensures
permanent separation of air
and water. Steel retaining
ring “seals” diaphragm
directly to tank shell.
The industry's most popular “standard” tank sizes are
44-gallon. Pump Mate offers 52-gallon tanks in the same
price range. So, a 52-gallon Pump Mate delivers 12%
higher drawdown than the industry standard. A 52-gallon
Pump Mate delivers 18% higher drawdown than standard!
In-Line Tanks
SPMDI Series tanks, available in 2, 4.6,
7.3 and 14-gallon sizes, are designed to
be supported by system piping (See
Typical Installations, page 4).
2-coat polymer water-side
lining, bonded to shell,
proven protection
against rust.
Rotating corrosion-resistant base
assures stability. Rotates for
easy alignment to connection.
Slotted and notched for proper
airflow, reduced condensation.
PRE-PRESSURIZED PUMP TANK OPERATION CYCLES
38 PSI
50 PSI
28 PSI
40 PSI
Start-up Cycle*
Diaphragm is pressed against
the bottom of the chamber.
* Based on 30-50 PSI operating system.
2
Fill Cycle*
Water is pumped into the reservoir, which forces the diaphragm
upward into the air chamber.
Hold Cycle*
Pump-cutoff pressure is attained.
Diaphragm reaches its uppermost
position. Reservoir is now filled to
its rated capacity.
Delivery Cycle*
Pump remains shut off while air
pressure in top chamber forces
diaphragm downward, delivering
water to syste m.

The charts below allow you
to easily select the right
free-standing tank for standard size pumps between
2-1/2 and 30 gallons in
capacity and for 20-40 PSI,
30-50 PSI and 40-60 PSI
pressure ranges. Minimum
run times shown (from
start-up) are 1 minute, 11/2 minutes and 2 minutes. For example, for a system that delivers 10 gpm at
30-50 PSI, with a minimumruntimeof1

that the proper tank is the

not be made
using Chart 1,
follow this procedure .
First find the “drawdown multiplier” by matching the
pump start-up and shut-off pressures on Chart 2. For
example, the multiplier for a 30-50 PSI pressure range
is .31. Next, insert the pump GPM capacity and
desired minimum run time into this formula:
PUMP GPM x Min. Run Time
Multiplier
To assume dependable Drawdown Volumes, and in
keeping with present industry practice, Drawdowns
are based on Boyles Law.
For example, using a 10 GPM pump, a one-minute
minimum run time, and a 30-50 PSI pressure range,
the formula is as follows:
10 x 1
.31
32.25 Minimum Tank Volume
=
Then, using Chart 3, select the tank that has a minimum volume that meets or exceeds your minimum
volume requirement, and supplies adequate drawdown at the required pressure range. Minimum drawdown equals Pump GPM x Minimum Run Time.
Therefore, in the above example, select the SPMD36S 36-gallon tank. It provides adequate drawdown at
30-50 PSI.

Free-Standing Series*
The standard installation, utilizing front entry, with gauge, relief
valve and pressure switch installed in
front
of tank.
Free-Standing Series With
Pump Mounted On Tank*
The pump can be mounted on tank using a universal
mounting base. The pump and base can be strapped to
the tank in the horizontal position, or mounted to the
tank in a vertical position.
In-Line Series*
The In-Line Series is designed to be supported by
system piping, either directly above the pump, or in
a convenient place in the piping system as close to
the pump as possible.
Universal Mounting Bracket
Standard on SPMDH
models.
* When pump and tank are in different locations, the pressure switch should be at the tank location.Orcompensating adjustment must be made for pressure loss due
to head of water, i.e., one PSI for every two feet of elevation.

“Glasslining,” a porcelain protective coating
to a steel tank interior, is the plumbing
industry’s most time-tested system protection. State Neptune Glasslined Pump Tanks
feature rolled-steel construction. State Water
Heaters is one of the world’s largest producers of glasslined tanks, and every Neptune
Tank is made in the U.S.A.
Other Neptune features include a 1-1/4"
NPT spud on top for motor mount or retention tank connections, a 1/4" switch or
gauge tapping on the air side of the tank, and
full-size 1-1/4" connections at all needed
locations.
