ProVore® PRG100 - Series Specifications 1.01 OPERATING CONDITIONS: Each submersible pump shall be rated at 1 hp volts phase 60 Hz. 3450 RPM. The unit shall produce G.P.M. at feet of total dynamic head. The submersible pump shall be capable of handling residential sewage and grinding it to a fine slurry, enabling it to be pumped over long distances in pipelines as small as 1.25" in diameter. The PRG series single stage submersible pump shall have a shut-off head of 50 feet and a maximum flow of 28 GPM @ 30 feet of total dynamic head. The pump shall be controlled with: A piggy back style on/off float switch (Single Phase Only). A NEMA 4X outdoor simplex control panel with three float switches and a high water alarm. A NEMA 1 indoor simplex control panel with three float switches and a high water alarm. A NEMA 4X outdoor duplex control panel with three float switches and a high water alarm. A NEMA 1 indoor duplex control panel with three float switches and a high water alarm. A NEMA 4X outdoor duplex control panel with four float switches and a high water alarm. A NEMA 1 indoor duplex control panel with four float switches and a high water alarm. 2.01 CONSTRUCTION: Each centrifugal grinder pump shall be equal to the c GO.. certified PRG Series Grinder pumps as manufactured by Liberty Pumps, Bergen NY. The castings shall be constructed of class 25 cast iron. The motor housing shall be oil filled to dissipate heat. Air filled motors shall not be considered equal since they do not properly dissipate heat from the motor. All mating parts shall be machined and sealed with a Buna-N o - ring. All fasteners exposed to the liquid shall be stainless steel. The motor shall be protected on the top side with sealed cord entry plate with molded pins to conduct electricity eliminating the ability of water to enter internally through the cord. The motor shall be protected on the lower side with a unitized hard face silicon carbide seal with stainless steel housings and spring. The upper and lower bearing shall be capable of handling all radial thrust loads. The lower bearing shall have the additional ability to handle the downward axial thrust produced by the impeller and cutters. The pump shall be furnished with stainless steel handle having a nitrile grip. 3.01 ELECTRICAL POWER CORD The submersible pump shall be supplied with 10 feet of multi -conductor power cord (25ftfor PRG101/102A-2/PRG101AV-2 models). It shall be cord type SJTW (1 -phase). The power cord shall be sized for the rated full load amps of the pump in accordance with the National Electric Code. The power cable shall not enter the motor housing directly but will conduct electricity to the motor by means of a water tight compression fitting cord plate assembly, with molded pins to conduct electricity. This will eliminate the ability of water to enter internally through the cord, by means of a damaged or wicking cord. 4.01 MOTORS Single phase motors shall be oil filled, capacitor start / capacitor run, class B insulated NEMA B design, rated for continuous duty. At maximum load the winding temperature shall not exceed 105 degrees C unsubmerged. Since air filled motors are not capable of dissipating heat they shall not be considered equal. Single phase pump motors shall have an integral thermal overload switch in the windings for protecting the motor. On all single phase models, the capacitor circuit shall be mounted internally and motors shall have an integral solid state starting circuit switch for switching the start winding off. 5.01 SEALS The pump shall have a unitized silicon carbide hard face seal with stainless steel housings and spring equal to Crane Type T -6a.
