  BoosterpaQs offer the following functions: • Closed-loop control Grundfos BoosterpaQ systems consist of 1-8 pumps with all necessary fittings and a Grundfos Control 2000 • Automatic shut-off at zero flow mounted on a common base frame, ready for installation. • Automatic cascade control of pumps The Control 2000 has its own base for large BoosterpaQs.
• Page 5
  Grundfos BoosterpaQ MSH maintains a pressure range by cutting in/out the half-size pump and the full-size pumps. The half-size pump will always start first. The half-size pump will be cut out again when a full-size pump is cut in. The operating range of the pumps will lie between the lines Hset and Hstop (cut-out pressure).
