Zoeller MX161 Explosion Proof Effluent Pump Buyers Guide & Review


Welcome to Inspector Pumphead Recommends! In this feature, I will be recommending a specific pump model and highlighting the features, specifications, and benefits of this pump. It could be a new product, a best seller, a seasonally appropriate pump, or one that is strongly recommended by the application engineers.

Let’s dive in!

Zoeller MX161 161-0106 Explosion Proof Effluent Pump

Part of the innovative X160 series, the Zoeller 161-0106 can be used for either residential or commercial dewatering/effluent applications in Class 1, Division 1, Group C, and D* environments.

Performance-wise, the Zoeller 161-0106 is built for high head residential and commercial effluent/dewatering applications. The Zoeller MX161 can be submerged in a maximum temperature of 104°F water continuously and can pass water with ¾” solids.

This is an excellent choice for effluent applications in areas where flammable vapors could be an issue.

Construction

Of course, being an explosion proof pump, the Zoeller MX161 is durable and built to withstand harsh environments where flammable vapors might be present.

The cover, motor adapter, and pump housing are all Class 30 cast iron. The shaft seal is composed of stainless steel wetted parts, carbon, and ceramic, while the float and vortex impeller are non-ferrous brass. The pump also features an innovative motor and electrical enclosures that reduce vapor ignition on the interior and exterior of the pump. Should flammable vapors inside the enclosures spark, the enclosures can contain the ignition and keep it from spreading. Moisture sensors are pre-wired into the motor housing.

The discharge is 1-½” NPT threaded, with an option for a flanged discharge attachment. The power cord is 25 ft. with five bare lead wires. All in all, this is an excellent pump that will perform well for any effluent or dewatering application in a hazardous area.

A UL-listed 5 wire power cord with sensor and power leads is included with the pump.

Hazardous Areas

*And now a brief word on hazardous areas, as defined by the NEC and NFPA:

Class I, Division 1: There are three different situations that could exist to classify an area as a Class I, Division 1 location:

–Ignitable concentrations of flammable gases or vapors may exist under normal operating conditions.
–Ignitable concentrations of such gases or vapors may exist frequently because of repair or maintenance operations or because of leakage.
–Breakdown or faulty operation of equipment or processes might release ignitable concentrations of flammable gases or vapors, and might also cause simultaneous failure of electric equipment.

Group C: Flammable gas, flammable liquid-produced vapor, or combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than or equal to 0.45mm or less than 0.75mm, or minimum igniting current ratio (MIC ratio) greater than 0.40 and less than or equal to 0.80. Example: Ethylene – 497:3.3.5.1.3.

Group D: Flammable gas, flammable liquid-produced vapor or combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than or equal to 0.75mm or minimum igniting current ratio (MIC ratio) greater than 0.80. Example: Propane – 497:3.3.5.1.4.
