WORKING PRINCIPLE

The series consists of PERIPHERAL PUMPS,so called because the peripheral edge of the impeeler contains numerous radial blades,designed to yield energy to the fluid beig pumped.The paricular shape of the blades rapidly tansfers redial recirculation motion to the fluid on entry to the pump between the impeller blades and the double channel,machined on each of the pump body.Since each of the numerous blades helps transfer energy,the fluid pressure increase progressively as it passes from the suction opening to the delivey opening,ensuring an even,non-pulsing flow and high accuradte mechanical machining during manufactore to prevent a drop in performance.

ZHEJIANG LANGYOU PUMP CO.,LTD.has been in the peripheral pump market sinc 1988 and hs developed an uneaqualled experience in optimizing design,This,together with great efforts in achieving fully automated protection processes,makes TOP one of the leading world industries in its field.

PUMP INSTALLATION AND APPLICATIONS

These pumps are suitable for handling clean water not containing abrasive particles and fluids which are not chemically aggressive to the pmp components.RELIABLE,ECONOMIC AND SIMPLE TO USE.THEY ARE SUITABLE FOR DOMESTIC APPLICATIONS AND THE AUTOMATIC DISTRIBUTION OF WATER FORM SUEGE TANKS,WATERING GARDENS AND FOR BOOSTING INSUFFICIENT MAINS WATER PRESS USE.

These pumps should be installed in a covered area,protected against the weather.

PERFORMANCE

The wide range of pumps in the series satifies the most various operating requirements with features such as :-high head with respect to power requirements;stable operating  curves,with small variations in delivery rates with respect to large variations in the pressure demand;high tolerance of the presence of entrained air in the liquid being pumped.

STRUCTURE CHARACTERISTICS

Cast iron PUMP BODY

Aluminum MOTOR BRACKET

BRASS IMPELLER,with radial perpheral blades,floating on the shaft.

Ceramic and graphite MECHANICAL SEAL.

MOTOR:the pumps are coupled directly to an asynchronous,high efficiency TOP induction motor of suitable size,which is quiet running,closed and externally ventilated ,with ((IMB3))structural shape,suitable for continuous duty.NSULATION class F(B up to 0.75kw).

The thermal cutout relay (motor protector)  is incorporated in single phase motors.

Three phase motors require an adquate external motor protector,with connections according to current standards.
