Progressive cavity pump joints
Progressive cavity pump universal joints from seepex Inc., are now available with ratings to 360 psig. This allows the pumps to be used on applications with high suction heads, low NPSHA applications with reverse rotation (common in vacuum condensation or suction lift applications) or in vertical pumps where the joints are exposed to the rated discharge pressure of the pumps. A new proprietary technology allows the joints to be hydraulically balanced and reinforced against implosion from high pressures. The joints are long lasting because they are positively sealed with an elastomer cover and two holding bands and lubricated with high temperature grease especially formulated for this service.
