Description
Burks 7CT7M Turbine Pump, 3/4 HP, 115/230V, 1 Phase
The Burks 7CT7M turbine pump is a 3/4 HP,
single-phase CT Series close-coupled regenerative turbine pump
for 60 Hz operation. This model uses a
115/230V ODP motor, bronze fitted construction,
1" NPT suction, 1" NPT discharge, and 3450 RPM operation.
Regenerative turbine pumps are commonly selected for applications that require
controlled flow at higher head conditions. Before ordering, confirm voltage,
phase, connection size, fluid temperature, suction conditions, and the required
duty point for your system. Browse other

Installation & Selection Tips
Confirm your electrical supply matches the 115/230V single-phase
motor requirement. Verify that the system piping matches the
1" NPT suction and 1" NPT discharge
connections, and confirm that the required flow and head conditions fall within
the pump performance range.
For boiler feed, condensate return, circulation, transfer, or other system
applications, confirm flow rate, total dynamic head, fluid temperature,
inlet pressure, suction conditions, and available NPSH before ordering.
