3.11.4 Suction and discharge connections. Suction and discharge connections shall be
6-inch 300 pound raised face flanges, in accordance with ANSI B16.5, and shall be fitted with
steel blind flanges including suitable gaskets to protect the pump connections during shipment
and periods of non-use. The pumps shall be furnished with pipe adapters for the suction and
discharge connections having a 300 pound raised face flange connection on one end and an
Inland Petroleum Distribution System (IPDS) 6 inch single groove connection, as shown in
figure 2, on the other end. The adapters shall be designed so that when attached to the suction
and discharge connections, the IPDS single groove ends are positioned 9.5 + 1.5 inches vertically
from the bottom of the skid. If the suction adapter is not identical to the discharge adapter, each
shall be labeled accordingly.
3.11.5 Casing vent lines. The pump casing vent lines shall be routed to a point at the edge of
the skid base and shall terminate in a single 3/4-inch pipe. The height of the pipe shall be
sufficient to allow a 10-inch vessel to be placed underneath.
3.11.6 Tapered pins. A tapered pin shall be provided on each of the two diagonally opposite
pump mounting feet to establish a bench mark for pump-driver alignment.
3.12 Engine. The engine shall be an industrial, turbocharged, diesel engine, selected in
accordance with MIL-STD-1410, class II. The engine shall deliver power at its continuous duty
rating to meet the pump requirements of 3.10. The engine shall be capable of operating on all
fuels specified in VV-F-800 and with JP-8 conforming to MIL-STD-83133 at all ambient
temperatures specified in 3.6.1 without degradation of reliability or durability. The engine shall

c. Fuel filters, primary, water separating type; secondary, with drain cock.
d. Manual engine controls to include a waterproof pushbutton starter switch and a
push-pull shutdown control (pull to stop).
e. Automatic engine shutdown controls in the event of engine overspeed, high coolant
temperature, low lubricant oil pressure, or pump low suction pressure (device with an
adjustable working range of 0-50 psig.
f. Spark-arresting muffler with guard.
g. Drain tube to permit draining the engine oil into a container without soiling other
components of the system.
h. Auxiliary charging receptacle conforming to MIL-C-62122 for recharging the
batteries from a remote power source without operation of the engine.
i. Cold weather starting aid conforming to MIL-E-52649, type 3.
j. Port to sample engine oil for testing.
k. Provisions to lubricate the turbocharger bearing prior to startup. Lubrication of the
