Introduction
Spring MS1's multiple combinations of pump head and motor power allow the selection of the optimal combination most suited to the specific application. The MS1 Series achieves flow rates between 1.45 and 170 gph with a pressure of up to 116 psi making it very flexible. The MS1 pumps have a spring return mechanism in a single aluminium housing. Each model can be adjusted to between 0-100% of the total flow rate. This can be done manually or automatically by using the AKTUA actuator which operates with a 4-20 mA signal. In addition, Spring MS1 pumps can be supplied with a single or three-phase electric motor with IP55 protection.
