Regenerative Turbine Pump with Canned Motor Y-2951-W-MM
Description
Hermetically aled centrifugal pump with can-ned motor.
Impeller (230) and inner magnet (847) are asmbled to the same shaft (211), the shaft is supported by a medium-lubricated sleeve bearing (310). The power transmission from motor to shaft is produced by a rotating field, generated by coils, directly to the inner magnet.
The can (816) parates the pumping chamber from the atmosphere. An integrated electronic circuit provides for the rotating field and controls the pump speed.
The drive is free from bearings and rotating com-ponents: No maintenance is necessary in standard operation.
Applications
The pump can be ud in the following fields of application, e.g.:
Temperature controlling and industrial cooling • cooling of machines, systems and production process
• cooling of industrial and medical lars • climatisation of control cabinets
• tempering devices in laboratory applications Further applications
• drinking water supply in railcars and on ships • etc.

0 Every operating point can be reached within
the characteristic fields by tting different drive parameters.
The characteristic fields are applicable for the delivery of water of 20 °C (68 °F) temperature and an ambient temperature of 20 °C (68 °F).
The tolerance of total head and capacity is ±10%, performance tolerance is +10%. If the property of the pumped media differs, the characteristic fields change.
The power consumption P1 specifies the electrical power input.
