Cozyel 12 GPM Air-Operated Air Diaphragm Double Diaphragm Pump Cast Iron 115 PSI Dual Diaphragm Air Pump Petroleum Fluids 1/2 inch Inlet/Outlet QBK-15

Air-Operated Double Diaphragm Pump 12GPM 1/2Inch Inlet And Outlet. The diaphragm pump features an externally serviceable air distribution system and all-bolted construction, with convenient operating, are widely used in various industries, such as petroleum, metallurgy, mining, coating material, printing, paper making, water treatment, automotive etc.
A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid..
Rugged construction - resists corrosion for reliable performance and long life.Bolted construction is designed for leak-free fluid handling..
Good abrasion resistance and heat resistance..
Easy access to ball checks and fluid caps for maintenance and repairs..

...ll types of weather with the flick of a switch. Heaters are switched and controled with a low voltage wall switch that is provided..
ECONOMICAL TO OPERATE: Highly efficient reflectors capture the radiant energy, and direct it to the patio area. Heats more area with less fuel than any other style of patio heater. LOW MAINTENANCE: No ceramic parts to break, or replace. Not thermocouples to replace. Emitter tubes do not glow cherry red, therefore are not fatigued to the point of premature failure..
