Our dry-running diaphragm pumps are characterized by high efficiency, low noise and good air tightness, and can be used as either a compressor or vacuum pump. Since some diaphragm pump applications are so specific, Gardner Denver also has an outstanding reputation for developing unique turnkey solutions, such as leak testing, vacuum plasma and special pump systems.
Although the principle of the diaphragm pump is quite simple, there is a skill to balancing the right combination of operating parameters and service free life, whilst achieving value for money.
Original equipment manufacturers (OEMs) know that performance and productivity is a function of the quality and dependability of diaphragm-pump components. That’s why so many original equipment manufacturers of medical equipment, laboratory, life science, environmental and automotive products have entrusted their reputations to Gardner Denver for more than 50 years.
To address the exacting specifications of many of these applications, such as patient monitoring, anaesthesia control, gas detection, personal protection, flue gas measurement and pipetting, Gardner Denver has created a complete line of small, lightweight, low-noise and maintenance-free, AC, DC or brushless DC motor driven diaphragm pumps Larger, more industrial type pumps deal with harsh operating conditions and can be specifically configured for corrosion resistance. Materials such as PTFE, Kalrez and viton are used where appropriate to maximize operational life.
Another critical materials consideration for many industries is resistance to the corrosion of seawater. The engineers at Gardner Denver understand that aluminum is a better metal than nickel-plated ductile cast iron or brass for diaphragm pumps operating in a saltwater environment. More importantly, they know that seawater corrosion is more than a function of the metal used in the parts; it is also a function of the velocity of the water. That’s why the Gardner Denver 8011 Series of diaphragm pumps are built with rugged aluminum parts; because seawater and fatigue resistance is essential for optimal performance. These maintenance-free, silent (50-54 dBA) and low-vibration pumps are also manufactured as specialized models for many applications, including autoclaves, analyzers, vacuum ovens, rotary evaporators, degassing and aspirators.
