• Integrated, adjustable pressure relief valve (bypass valve) for pipe protection
• The rugged pump design with only two housing parts allows simple, quick and efficient maintenance and servicing
• The gearwheels pressed on the shaft are axially and radially supported in the housing and in the cover
• The torque is transmitted from the driving shaft with the driving gear wheel to the countershaft with the mating gear wheel
• The pumping effect of this gear pump is achieved by means of the opposite rotation of the two gear wheels
• Very compact design
• Exceptional high suction performance
• Pump is suitable for tank and wall mounting
• Pump is designed for use in conjunction with pipe lines up to 70 meters, depending on cross section of pipe line
