HP is the Grundfos SP motor rating for that output current at that supply voltage, from the Grundfos Groundwater Guide; select by the motor's service-factor amps. A double dash means Grundfos publishes no SP motor rating at that current.
The pressure transducer (0-120 PSI, 1/2 in NPT, part 92506685) is sold separately and is listed under Grundfos SQ and SQE Pump Accessories. Grundfos does not publish a sine-wave filter pairing for the IP66 drives in its price book; request a system-specific filter selection where a filter is required.
