JOHNSON PUMP Air Operated Diaphragm Pumps

TopAir – Reliability, performance and quality – based on more than 40 years of experience in manufacturing air operated diaphragm pumps Diaphragm pumps are used in all types of industries for transporting a wide variety of liquids. Clean or polluted, thin or viscous, abrasive or aggressive. The wide use of an AODD pump is the main reason for its growing popularity. Johnson Pump is manufacturing pumps at five locations world-wide. We are proud of being able to say that we have 70 years of experience of developing, manufacturing and marketing pumps. We offer our customers solutions in liquid trans-...

TopAir – The multi-purpose pump for solutions in all industries TopAir will pump any liquid which flows or moves through a pipe – from clear water and thin volatile liquids to highly viscous and abrasive or chemically aggressive liquids. The survey below provides an outline of applications possible with the TopAir pumps. Ceramics Clay, enamel clay, glazes. Chemical Industry Acids, alkalis, suspensions, stabilisers, resins, latex, solvents, electroplating baths, filter press operation and dispersions. Construction Sump and pit drainage, cement slurry, concrete slurry, rock slurry, tile adhesive,...

Accessories Pulsation damper Diaphragm leak sensor An air driven diaphragm pump creates a pulsating flow, which is no problem in most applications . However, in some cases a reduced pulsation is required and the pulsation damper will reduce the pulses up to 75%. The leak sensor protects the diaphragm pump from corrosive, aggressive or other harmful fluids. High performance generator in combination with an EDP1 diaphragm pump will create a constant flow – an accurate measuring unit. Electronic stroke counter for dosing FRL – Filter, Regulator and Lubricator Flange connections All kind of outlet...
