PART II - PRODUCTS 
 
2.01	GENERAL DESCRIPTION 
 
	The pumps shall be horizontal close-coupled regenerative turbine pumps, Aurora Pump series 130 or pre-approved equal.  Pre-approval must be obtained a minimum of ten days before bid date. 
 
2.02	MATERIALS OF CONSTRUCTION 
 
	Casing.......................Cast Iron (ASTM A48) 
	Impeller.....................Bronze (ASTM B62) 
	Shaft........................Stainless Steel (AISI 416) 
	Impeller Sleeve..............Bronze (ASTM B62) 
	Channel Rings................Cast Iron (ASTM A48) 
 
2.03	CASING 
 
	The casing shall have a top side suction inlet and a center-line discharge outlet with an integral stuffing box cover and motor mounting bracket and removable front cover for Series 133 pumps. The suction inlet and discharge outlet shall be NPT threaded.  The casing shall bolt directly to the motor.


2.04	IMPELLER 
 
	The impeller shall be of the regenerative turbine or periphery-vane type, with the pumping vanes machined on both sides of the impeller to balance hydraulic thrust.  The impeller shall be keyed to the shaft, but not locked in place to allow the impeller to self-balance between the channel rings.  Balancing holes shall be machined into the impeller to facilitate this floating action as required.
 
2.05	SHAFT 
 
	The impeller shall be direct-coupled to the motor shaft.  The motor shall be machined to provide a keyway, and drilled and tapped to accept the impeller sleeve fastener.  Stub shafts are not acceptable.
 
2.06	CHANNEL RINGS 
 
	The channel rings shall have an individual water passageway machined, and cleaned of all burrs, trimmings and irregularities.
 
2.07	IMPELLER SLEEVE 
 
	The pump shall include an impeller sleeve fitted over and keyed to the shaft to minimize shaft wear.  The impeller shall fit over this sleeve.  The sleeve shall be locked to the shaft by means of a washer and capscrew at the shaft end.  The mechanical seal spring shall fit onto the impeller sleeve.
 
2.08	MECHANICAL SEAL 
 
	Shaft sealing shall be accomplished by means of a mechanical seal with a Ni-Resist seat, carbon washer, Buna-N elastomer, and stainless steel metal parts.
 
2.09	MOTOR 
 
	The motor shall conform to the latest NEMA Standards, and shall have to the following characteristics: 
 
	Enclosure.....................Open Drip Proof/TEFC/X-Proof 
	Number of Phases..............Three 
	Cycles........................60 Hz. 
	Voltages......................230/460 Volt 
	Speed.........................3600 RPM 
	Horsepower....................? hp 
 
	Each motor shall have a sufficient horsepower rating to operate the pump at any point on the pump's head-capacity curve without overloading the nameplate horsepower rating of the motor.  The motor shall have a service factor of at least 1.15.  The service factor is reserved for variations in voltage and frequency.
 
 
PART III - PERFORMANCE 
 
3.01	CONDITIONS OF SERVICE 
 
	The following conditions of service shall be strictly adhered to: 
 
	Number of Units......................?		 
	Type of Drive........................? (variable or constant) 
	Discharge Size.......................1.5 in, minimum	 
	Suction Size.........................2 in, minimum	 
	Design Capacity...................... US gpm	 
	Design Head.......................... ft	 
	Efficiency at Design................. %, minimum	 
	Rotative Speed.......................3500 RPM, maximum	 
	Shut-off Head........................905 ft, minimum	 
	Drive Horsepower.....................4.28 hp, minimum	 
	NPSHR at Design...................... ft, maximum	 
 
3.02	INSPECTION AND FACTORY TESTS 
 
	Each regenerative turbine pump furnished under these specifications shall be tested at the factory to verify individual performance (VIP).  Certified copies of all test reports shall be submitted to the Engineer for approval prior to shipment.

3.03	INSTALLATION AND ACCEPTANCE TESTS  
 
A.	The pumping units shall be installed in accordance with the instructions of the manufacturer and as shown on the drawings by the Contractor. 
 
B.	Installation shall include furnishing the required oil and grease for initial operation.  The grades of oil and grease shall be in accordance with the manufacturer's recommendations.
