1. Pressure relief valves
   These pumps can be delivered with built-on pressure relief
   valves. This brochure does not provide valve
   characteristic curves and sectional drawings; these must be
   requested separay.
   If pumps are requested without an installed pressure relief
   valve, overload protection must be provided in the cont-roller or
   as a pipeline-mounted valve .
   Drive
   The pumps can be coupled to different types of electric motors
   or to other drive machines either directly (series SNH, SNGH),
   by way of a motor bracket (series SNS, SNGS), or by way of
   wall-mounted or foot-mounted brackets (series SNF, SNGF).
   In most cases, the pumps are meant for use with surfacecooled three-phase squirrel-cage motors, design type B3 or
   V1; degree of protection IP 55 according to IEC standard,
   insulation class B, motor windings for 400 VΔ, 50 or 60 Hz
