Long Service Life Water Circulation Pump Low Fuel With Strong Driving Force

Structural Characteristics:

• AISI 304 stainless steel PUMP BODY with UNI ISO 228/1 gas threaded suction and delivery ports.
• AISI 304 stainless steel back plate serving also as mechanical seal housing.
• General Electric® Noryl® GFN2V technopolymer EJECTOR UNIT (approved for drinking water).
• Centrifugal radial flow type IMPELLER in General Electric® Noryl® GFN2V technopolymer (approved for drinking water).
• AISI 416 stainless steel MOTOR SHAFT
• Ceramic and graphite MECHANICAL SEAL.
• MOTOR: pumps are coupled directly to an asynchronous, high efficiency PEDROLLO induction motor of suitable size, which is quiet running, closed and externally ventilated, suitable for continuous duty INSULATION class B (class F only 0.90 kW single phase).
  A thermal cutout relay (motor protector) is incorporated in single phase motors. Three phase motors require an adequate external motor protector connected according to current standards.
• CONSTRUCTION AND SAFETY STANDARDS in compliance with EN 60 335-1 (IEC 335-1, CEI 61-150) EN 60034-1 (IEC 34-1, CEI 2-3).
• REGISTERED MODEL

Use And Maintenance:

1. You should make the pump working in the standard rotate speed in use process, don't speed up at will, in order to avoid potential safety hazard and impact the useful life of the pump.

2. Direct coupled type pump units:the chassis must remain stable, so as not to damage the coupling.
Belt wheel type pump units:the two pulleys must be aligned, the belt loose or tighten must be moderate. If the pump doesn't turn, it is generally because the impeller-ring get rusty, you can use the mallet knocking the coupling axially.Pump mounting height(in order to suction the water tank as the base)should be less than the permit smoking on 1-2meter high vacuum.

3. You should stop the engine if you discover abnormalities(such as noise, shock, hydraulic discharge descend etc.),and attention the bearing heat up, the temperature can't exceed 75°C.
If stop using for a long time, you should discharge the water in the pump, overhaul and oil, keep it in a dry and ventilate shade.
In winter, you should discharge the water at once when you stop using it in case frost crack.After the pump every 1000 hours operating time, you should take down and clean the bearing, and exchange quick-wear parts.
