The Nastec VASCO range of variable speed drives are cost-effective, fully featured motor mounted units (wall mounting kit available) which can be retrofitted to many types of pump. These devices allow a pump to operate at a lower speed than its maximum when full power is not required. The leads to significant energy savings and reduced wear on the pump. Up to 8 of these units can be connected in cascade mode to control multi-pump systems. A pressure transducer, dry run protection, soft start and duty pump changeover timer are also included.
