3SDX12F1KC EXPL. PROOF SUB. SEWAGE PUMP 1.5HP 230V 1PH 2.5"

Goulds 3SDX Explosion Proof Submersible Sewage Pump Model: 3SDX12F1KC, 1.5HP, 5.81" Impeller Diameter, 1 Phase, 230 Volts, 1750 RPM, 11.6 SF Amps. Explosion Proof Submersible Sewage Pump Class 1, Groups C and D Hazardous Locations FEATURES ■ Impeller: Cast iron, ASTM A48, Class 30, two vane semi-open, non-clog design with pump out vanes for mechanical seal protection. Computer balanced for smooth operation. Silicon bronze impeller is an option. ■ Casing: Heavy duty gray cast iron, ASTM A48, Class 30. Volute type casing with 3”, 125#, flanged, horizontal discharge conforming to ANSI standards. Compatible with A10-30 cast iron or A10-30B cast iron and brass (non-sparking) slide rail assembly. ■ Seals: Tandem mechanical seal system in an oil filled seal chamber. Each seal operates independently to ensure fail safe performance. Standard seals are carbon rotary and ceramic stationary. Outer seals are designed for easy replacement. Optional seals are available. ■ Seal Sensor Probes: Pump has a standard dual probe moisture detection system located in an oil filled seal chamber. The sensor leads must be connected to a “seal fail circuit” in the control panel. APPLICATIONS Designed for a variety of hazardous commercial and industrial applications such as: • Sewage systems • Flood and pollution control • Dewatering and effluent • Hospitals • Trailer courts • Hotels and motels Specifications: Pump: • Maximum solid size: 2.5” • Discharge size: 3” ANSI 125# Flange • Maximum capacity: 550 GPM • Maximum total head: 67’ Motor Specifications: • Maximum ambient temperature: 40º C (104º F) • Rated for continuous duty with motor fully submerged • Service Factor: 1.15 • HP range: Single phase: 1.5 to 3 HP Three phase: 1.5 to 7.5 HP • 60 Hz Voltages available: Single phase: 230 Three phase: 200, 230, 460 and 575 • Insulation: Class F • Single row ball bearings MOTOR FEATURES: • Explosion Proof Motor: For use in hazardous locations. Rated Class 1, Groups C & D. • Standards: All motors conform to the latest requirements of NEMA, IEEE, ANSI and NEC standards. • Air filled motor • Class F insulation • Thermal Protection System: The motor is equipped with two automatic reset on-winding thermostats to protect it from high temperatures. • Operating Design: Motors are designed for continuous submerged operation. The maximum allowable run time in air is 15 minutes. • Bearings: Single row greased for life sealed bearings. Rated for minimum L10 life of 17,500 hours. The bearings are designed to carry the radial and thrust loads. • Cable Entry: Power and control cables are epoxy encapsulated to prevent wicking even if the cable jacket is punctured. Buna-N grommets provide an additional cable seal. • Shaft: The shaft is 416 stainless steel. • Power and Control Cables: Standard length is 25', optional 50' is available. The power leads are sized from 14/4 to 8/4 depending on HP and voltage, rated as SOW and SOOW. The control cable is 18/5 SOW cable. CONTROL PANEL REQUIRMENTS: To maintain warranty coverage and agency listings, Control Panels must have: • Moisture Detection System – to warn of a seal failure. • Thermal Protection System – winding thermostats open the pilot circuit of the magnetic motor controller before dangerous temperatures are reached. • Overload (Over Current) Protection – Class 10, quick-trip type overload protection must be provided in both three phase and single phase controls. • Intrinsically Safe Relays – use “intrinsically safe relays” in a Class 1 environment to power the float switches. They eliminate the danger of a spark if a switch cord becomes damaged. Intrinsically Safe Relays are available as an option from most panel suppliers. Other level control systems are available and may be applicable for this service, consult with your control manufacturer. • Single Phase Capacitor Box – a capacitor box is supplied with all single phase pumps. It must be wired to a control panel containing the items listed previously. Goulds Pumps control panels with the capacitors built-in are available. Typical Control Option: • Guaranteed Pump Submergence Float – Many engineers specify a redundant OFF float or a Guaranteed Pump Submergence Circuit. This provides a second OFF float as protection from “OFF” float failure or hang up which protects the pump(s) from running dry.
