SECTION 23 12 13
A.General Requirements:
1.Provide separately mounted direct drive duplex oil pump set. Each pump shall be equipped with relief valve, (2) check valves, basket type oil filter, pressure gauges.
2.Provide drip pan and angle iron wall bracket.
3.Provide a duplex set of fuel oil circulating pumps as drawn to serve the boiler burner(s). These pumps shall each be full size and designed to circulate No. 2 fuel oil from the storage tank to the burner(s).
B.Pump Casings: Pump casings shall be precision cast iron and shall be designed to permit replacement of wearing parts. Pump casings shall be of uniform quality and free from blowholes, porosity, hard spots, shrinkage defects, cracks, and other injurious defects. Defects in casings shall not be repaired, except when such work is approved and is done by or under the supervision of the pump manufacturer, and then only when the defects are small and do not adversely affect the strength or use of the casing.
C.Impellers: Rotor and idler shall be machine ground to match for positive displacement of fuel oil. Idler shall also be ground to match pump casing.
D.Rotor and Shaft: High grade steel, accurately machined. Shaft shall be of sufficient strength to perform the work required.
E.Idler and Idler Pin: High grade steel, accurately machined, and shall be of sufficient strength to perform the work required.
F.Mechanical Seal: Carbongraphite mechanical seal shall have a bronze bushing for the mechanical seal seat.
G.Relief Valve: Furnish pump with an integral relief valve mounted on cast iron casing.
2.04 DIRECT DRIVE ASSEMBLY
A.Base: Mount pump and motor on a formed steel base.
B.Pump and Drive Assembly: Bolt pump assembly to step on base. Motor and pump shaft shall be aligned and joined using a heavy duty, flexible type coupling keyed and locked to shaft. Coupling faces shall be machined perpendicular to shaft axis. Disconnecting couplings shall be accomplished without the driver half or the pump half of coupling from shaft.
C.Electric Motors: Bolt motor to steel pump base and align with pump shaft. Each pump shall be driven by a continuous duty, open dripproof electric motor. See Section 230513, Electrical Motor Schedule, or the equipment schedule for voltage and rpm requirements. See Section 230513 for motor minimum efficiency.
