The Model 5701 metering pump is a hydraulically actuated non-lost motion (amplitude modulated) diaphragm design. The unique method of actuation by means of a rotating plunger provides smoother, quieter operation at less than 100% capacity. The sine wave characteristics minimize back lash and shock loads to the process system. The Model 5701 is one of the most long lasting pumps in the industry. The pump will provide reliability in the most heaviest workload environments, such as mining, nuclear plants, power plants and refineries/petroleum applications. The 5701 meets API 675 standards.
