ustang Manufacturing Co. now is offering an optional pressurized cab on three current compact track-loader models: MTL16, MTL20 and MTL25. The pressurization is similar to modern, upscale agricultural cabs, the maker says. The new cabs virtually eliminate entry of dust, dirt and debris and reduce noise. The upgraded heating and air-conditioning features six adjustable louvers and easily maintained filters on air intakes, keeping clean air flowing to the operator. A defroster vent is located near the front cab door for cold-weather use. ubaru introduces the PTX301D diaphragm pump to its lines of centrifugal, high-pressure, trash and semi-trash pumps. This new model features 3-in.-diameter suction and discharge ports and pumps up to 250 gallons per minute at a maximum pressure of 21psi. It is self priming and has a maximum suction lift of 25 ft and maximum lift head of 49 ft. The pump is powered by a 7 hp Subaru EX21 air-cooled four-cycle gas engine. he Volvo Pipelayer is intended for applications in the onshore oil and gas industry, and features a full 360-degree radius of operation. Five models are available, with load capacities ranging from 20 tonnes to 150 tonnes. The pipelayer’s low center of gravity, wide gauge and centered boom allow the high maximum-load capacity.  he Phoenix Solar Water Heater integrates an efficient, solar-powered heating element with a gas-fired backup system to meet hot-water demands regardless of insolation conditions. The sealed- combustion, direct-vent unit provides domestic hot water and has side taps in the jacket to deliver space heating. It draws most of its heat from heat exchanger coils at the base connected to solar panels on a rooftop. Should the coils be unable to heat the water sufficiently, a gas-fired modulating burner provides the heat needed to finish the job. The Phoenix heaters are available in 80- and 119-gallon tank capacities.
