$(document).ready(function(){ $("td").css("border", "1px solid black") }); 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. Specs Model Discharge HP Voltage Phase GPM Max. Head Cord Mode 161-0106 1.5" NPT Fl. 1/2 115 1 100 56' 25' Auto 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.

The Zoeller 53-0001 is part of the versatile “Mighty-Mate” series of submersible pumps. Each pump in the Zoeller 50 series can easily be configured to act as either a sump pump or an effluent pump for a septic tank system, depending on your need. Each pump in this series is durable while remaining lightweight, compact, and easy to install. A particular point of emphasis regarding the construction is the importance of materials that can withstand the corrosive elements sometimes found in groundwater or graywater. The models 53 and 57 have a base cast iron construction, while the models 55 and 59 are made with bronze. The model 53 differs from the 57 in that the base is made of a special engineered thermoplastic base. The thermoplastic base is designed to protect the pump from possible rust damage. The screws, switch, arm guard, and handle are all stainless steel. In the interest of eliminating weak points, no sheet metal parts susceptible to rust are present in the construction of the pump. The 53 also features an engineered glass-filled plastic impeller with metal insert which protects from rust damage and is simple (as well as cost effective) to replace. The cherry on top of the cast iron sundae is the epoxy powder coat finish for additional corrosion resistance that was applied to each pump in construction. Each unit is also pressure tested All in all, if you are looking for an effluent pump that will last you a long time, the 53-0001 is an excellent choice. Besides the durable construction type, there are plenty of other features and benefits that make this an excellent choice for your sump or effluent application. A solid buoyant polypropylene float activates the pump, which operates at .3 HP, and either 115 or 230 volts. A watertight neoprene ring is inserted between the motor and pump housing. The motor itself runs at 1550 RPM and is oil-filled and hermetically sealed.  The sewage will be exported through a 1-1/2" NPT threaded discharge port. The model 53 is ideal for residential and light commercial applications with less than 20 feet of lift, which is probably why it is our best-selling Zoeller pump.
