FEATURES
Goulds 3SDX Explosion Proof Submersible Sewage Pump
This is an explosion proof, submersible sewage pump for use in hazardous locations rated Class 1, Division 1, Groups C & D. Pump has a 2.5 inch maximum solid handling capability.
Features
- Cast iron, ASTM A48, Class 30, two vane semi-open, non-clog impeller design with pump out vanes for mechanical seal protection
- Heavy duty gray cast iron, ASTM A48, Class 30 casing. 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
- 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
- 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
- Motor is designed for continuous submerged operation and the maximum allowable runtime in air is 15 minutes
- Air filled, Class F insulation motor
- Motor conforms to the latest requirements of NEMA, IEEE, ANSI and NEC standards
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
Control Panel Requirements
- 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 control panel
- Intrinsically safe relays – use "intrinsically safe relays" in a Class 1, Division 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.
- 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.

Goulds 3SDX series explosion proof sewage pumps are designed to move wastewater in potentially hazardous locations*, specifically in commercial and light industrial applications. Common application locations include sewage systems, flood and pollution control systems, in hospitals, trailer courts, hotels and motels. These pumps are submersible and capable of handling 2.5" maximum waste solids. The Goulds 3SDX series sewage pumps are listed to operate in Class 1, Group C and Group D hazardous locations.
The important thing with explosion proof pumps is that the construction components must be non-sparking. To that end, the both the volute and impeller of the Goulds 3SDX series is made of heavy duty gray cast iron (ASTM A48 Class 30). The tandem mechanical seals are carbon rotary and ceramic stationary contained in an oil-filled chamber. Each pump also has a dual probe moisture detection system in the chamber. The motor conforms to the latest NEMA, NEC, IEEE and ANSI standards. The rugged components and careful construction ensure safe operation and consistent wastewater transport in a hazardous location. All models include a 25 ft. power cord. *Hazardous locations are classified by the National Fire Protection Association (NFPA) and the National Electric Code (NEC). Broadly speaking, a hazardous location is one in which gases or vapors may be present in the air, in quantities sufficient enough to produce sparks or ignition.Goulds 3SDX Series Explosion Proof Sewage Pumps |
