Hale Fyr Port - Manual (Page 8)

DESCRIPTION
GENERAL:
The FYR PORT is a lightweight, portable, centrifugal pump mounted either on
skids or in a wraparound frame. The pumping unit consists of a Hale 20FP single stage
centrifugal pump close coupled to an air cooled, 2 cycle, single cylinder, gasoline
engine. The unit includes an automatic rewind starter, a spark arresting muffler, engine
overspeed control switch, priming pump and priming valve. It is intended for pumping
water from draft, relay, or hydrant. The unit will deliver discharge pressures to 220
PSIG and flows to 75 GPM from draft.
The FYR PORT pumping unit consists of 6 major subassemblies; the engine,
pump, priming system, mounting base, overspeed control switch and wraparound
frame.
ENGINE:
The lightweight engine is a single cylinder, 2 cycle, air-cooled version producing
@ 8 hp (6 Kw) from its 8.2 cu. inch (134 cc) displacement using a gasoline/oil mixture
fuel.
The engine is equipped with water resistant solid state ignition, a pressure
carburetor with built-in fuel pump, and an on/off ignition toggle switch.
The engine’s interior is protected from impurities by the use of a wire mesh
element air filter, a 75 micron in-line fuel filter, and an integral fuel strainer built into the
fuel pump. PUMP:
The engine crankshaft extension serves as the pump shaft with an enclosed type
bronze impeller mounted directly on the shaft. The shaft is protected against corrosion
by a bronze sleeve, an ‘’O”-ring, and a mechanical type, self-lubricating and adjusting
seal. The impeller is hydraulically sealed by a replaceable, patented, floating, bronze
clearance ring located in the inlet of the aluminum volute body. . The volute body is
attached to the cast aluminum pump head by four mounting screws.
The pump head, which serves as the mounting bracket for the pump and engine
assembly, is attached to the mounting base with rubber vibration and shock mounts. It
also incorporates a handle for positioning the unit or carrying short distances.
The pump inlet and discharge connections are either 1 1/2" male national fire hose
threads (NST), or 1 1/2" metric threads (ISO 228/1-G 1 1/2 A).
PRIMING SYSTEM:
The priming pump is a hand operated piston pump. Its purpose is to remove air
from the pump allowing atmospheric pressure to push water through the inlet hose into
the pump.
A priming valve is included which controls air flow through the priming line.
