K-TECH double diaphragm pump is an air pump that uses an air pump to control compressed air back and forth between two sides of the pump. Diaphragm pumps can pump low, medium or high viscosity liquids as well as liquids containing suspended solids. K-TECH AODD pumps are versatile and reliable pumps suitable for use in a variety of industries. Some applications of AODD pumps include chemical processing, wastewater treatment, mining dewatering, paint and ink production, and food distribution. A K-TECH double diaphragm pump is a variable displacement pump that uses two reciprocating flexible diaphragms, thus creating a temporary chamber that draws liquid into and discharges it from the pump. The diaphragm acts as a wall separating air and liquid.
