Mechanical Seal Vertical Multistage Centrifugal Pump

The FDLF, FDL, and FDLL series are non-self-priming vertical multistage centrifugal pumps, which are supplied as standard with motors. Designed as inline types, their suction and discharge ports are positioned on the same plane at the pump base. All models come equipped with maintenance-free cartridge-type mechanical seals.

Motor

FDLF, FDL, FDLL are fitted with totally enclosed fan-cooled, 2-pole, three-phase standard motors.

From 0.37~2.2kw, pumps are also available with single-phase motors. (1*220~230V/240V).

Motor Protection

Single-phase motor has a built-in thermal overload switch.

Three-phase motor must be connected to a motor protective circuit breaker according to local regulations.

Ambient temperature

+40℃ should be the max environmental temperature. If exceed +40℃, the motor will be burned out due to over-high temperature.

If installing the motor at the place that more than 1000 meters above the sea level, due to low air density, it will make the motor cooling effect in bad condition. So motor rated output power (P) will be reduced.

Under the above conditions, it is necessary to use a motor with higher rated output.
