The Importance of Reliability in Diaphragm Pumps

Reliability is the quality of being trustworthy or of performing consistently well. Here at Parker, we’ve made reliability the focus of our products since the company was established; this has made Parker’s products synonymous with reliability. The new BTX-Connect diaphragm pump meets next-generation manufacturers' needs for reliability, portability, noise reduction, and adds additional advanced technology that is revolutionizing miniature diaphragm pumps.

 

Reliability meets innovation

The Connect motor features the newest technologies in the miniature diaphragm pump industry. The Connect motor is a brushless motor with a patented motor bearing design that is key to the pump's reliability. The only component that wears overtime in a brushless DC motor are bearings, unlike brushed motors that have brushes that mechanically connect the rotor and are consumed over time. The bearing system of the motor is critical in pumps because of the reciprocating radial load on the motor shaft. The BTX-Connect uses a custom bearing assembly system designed to remove all of the bearing internal play; this ensures a longer lifespan and significant noise reduction. Additionally, the BTX pump family includes a proprietary advanced elastomer material, which is specifically designed to withstand the constant flexing and loading within the diaphragm pump enabling the pump system to go well beyond 15,000 hours of continuous use. 

 

Advanced serial communication

When designing the BTX-Connect pump, we considered the need for digital communication. Prior to the BTX miniature diaphragm pump, most pumps only had analog methods of speed control, PWM, 0-5V input, or on/off. The BTX breaks new ground by offering the option of connecting with a serial UART (Universal Asynchronous Receiver/Transmitter) that can provide motor speed measurements, internal temp, and fail-safe shutdown conditions if over temperature or over-current occurs. This is ideal for monitoring the pump's performance during the pump's lifespan.

In addition to all these standard features, the BTX offers accessories that can be purchased separately, including the EZ-Mount base and Filter-Muffler. The EZ-Mount base enables easy installation in instruments and rubber isolators that reduce vibration. The Filter-Muffler offers even more noise reduction by filtering up to 10 microns. This pump is well suited for hospitals and in-home devices when patients require less noise and distractions.
