Section SOLIDS HANDLING Page 505 Specifications — Solids Handling 3" SOLIDS HANDLING HAZARDOUS LOCATION SUBMERSIBLE SEWAGE PUMPS GENERAL Contractor shall furnish all labor, materials, equipment and incidentals required to provide 2 solids handling submersible centrifugal sewage pump(s)as specified herein. (OPTIONAL) Pump shall be equipped with stainless steel nameplate,stating the unit is accepted for use in NEC class 1,division 1, groups C,D hazardous locations with third party,Factory Mutual,approval. OPERATING CONDITIONS Each pump shall be rated_2 HP, volts, phase, hertz, and_1150_RPM. The unit shall produce_100_U.S.GPM at�20 feet TDH,with a minimum pump efficiency of 40_% .The pump shall be capable of handling a_3" " spherical solid.The pump shall be non-overloading throughout the entire range of operation without employing service factor.The pump shall reserve a minimum service factor of 1.20.The performance curve submitted for approval shall state in addition to head and capacity performance,the pump efficiency,solid handling capacity,and reflect motor service factor. CONSTRUCTION The pump shall be a centrifugal, solids handling, submersible, wastewater type, model _S3NX200_ as manufactured by Hydromatic Pump. The pump volute,motor and seal housing shall be high quality gray cast iron, ASTM A-48, Class 30.The pump discharge shall be fitted with a 3"standard ASA 125 lb.flange,faced and drilled.All external mating parts shall be machined and Nitrile 0-ring sealed on a beveled edge.All mating surfaces shall be flame-proof joints with special labyrinth joint to prevent a flame or spark to travel to the media being pumped.Gaskets shall not be acceptable.All fasteners exposed to the pumped liquids shall be 300 series stainless steel. ELECTRICAL POWER CORD Electrical power cord shall be SOOW or W,water resistant 600V,90°C,UL and CSA approved and applied dependent on amp draw for size. The pump shall be triple protected with a compression fitting and two epoxy potted areas at the power cord entry to the pump. A separation between the junction box area of the pump and the motor by a stator lead sealing gland or terminal board shall not be acceptable. The power cable entry into the cord cap assembly shall first be made with a compression fitting.Each individual lead shall be stripped down to bare wire at staggered intervals,and each strand shall be individually separated.This area of the cord cap shall then be filled with an epoxy compound potting which will prevent water contamination to gain entry even in the event of wicking or capillary attraction. The power cord leads shall then be connected to the motor leads with extra heavy connectors having brass inserts with a screwed wire- to-wire connection,rather than a terminal board that allows for possible leaks. The connection box wiring shall be separated from the motor housing wiring by stripping each lead down to bare wire,at staggered intervals,and separating each strand.This area shall be filled with an epoxy compound potting.Fiberglass terminal boards,which are subject to heat fatigue and cracking and which may lead to possible leaks,shall not be acceptable. The cord cap assembly where bolted to the connection box assembly and the connection box assembly where bolted to the motor housing shall each be sealed with a Nitrile 0-ring on a beveled edge to assure proper sealing. 414 PENTAIR HYDROMATIC° October ©2014 Pentair Ltd.
