Installation of Optional Accessories
Cycle Counter
The cycle counter is installed by screwing the pneumatic cylinder into one of the ¼” NPT
connections on top of the cover flange. The force of the pressurizing gas lifts the counter
arm for each cycle.
Freeze Protection Drain Valve
If the pump is to be installed outside, or anywhere that freezing is a threat, a Freeze
Protection Drain Valve should be installed on the ½” NPT drain connection on the bottom
of the tank. A pipe should be installed after the drain valve so that the discharge is visible.
See the instructions provided with the valve for more detailed installation directions.
Gauge Glass Assembly
2 Valves, 2 Rods, 1 Glass, 2 ¾” NPT Short Nipples, and 2 ¾” NPT Unions
This assembly is installed on the two (2) ¾” NPT connections on the front of the tank. The
valve with the drain connection must be installed in the bottom connection. The ¾” short
nipples and unions are threaded into the top and bottom tank connections. The valve is
threaded into the mating part of the ¾” union. It is very important that the top and bottom
valves line up before the glass is installed, or else the glass will break. The glass is installed
into the bottom valve, and the top valve is fitted over the top of the glass, and the union is
tightened. Tighten the two (2) fittings that hold the glass and install the guard rods.
Insulation Blanket
Wrap the main blanket piece around the pump tank so that the opening is on the same
side as the two (2) ¾” NPT couplings on the front of the tank. Fasten the front seam and
the two (2) end pieces, (if required) using the supplied stainless steel wire.
Pressure Gauge
Install the pressure gauge, with the syphon loop (pigtail), in one of the ¼” NPT connections
on the top of the cover flange.
Pressure Reducing Valve
The PRV must be installed upstream of the pump mechanism on the motive gas supply line.
The pressure must be regulated below 200 psig, unless a special tank has been ordered. See
the instructions provided with the valve for more detailed installation instructions.
Safety Relief Valve
A safety relief valve set at or below 200 psig, and a pressure gauge should also be installed
between the PRV and the pressure valve connection on to of the cover flange. This will
protect the pump in case the PRV fails. See the instructions provided with the valve for
more detailed installation instructions.
