The 'Draco' features a range of robust, compact and reliable submersible pumps, particularly suitable for effective handling of sewage and wastewater containing fecal or fibrous matter in a wide range of applications in both commercial buildings and inductrial plants. The hyfraulics with the various impeller options, ensures a blockage-free operation.
Draco, available in both 2 or 4-pole motor, covers a wide range of flowrates and heads.
The Draco pumps are designed for permanent submerged installation, e.g. by means of an auto coupling or guide rail system; or for free-standing installation on a ring stand with a flexible pipe connection.
Available in VCT or H07RN-F or SJOW/SOW. Variable length of cable is available upon request.
Expoxy resin sealed cable base to prevent the intrusion of moisture into motor through the core wires.
The 'auto-cut' protector, a standard feature for all motor sizes of 7.5kW and below, is integrated in the motor. It protects the motor from 'burning' by automatically cutting off the motor circuit in the event of power surge or excessive heat built-up. The 'auto-protector' switch automatically restarts the motor once the temperature drops to about 60~70oC; or when the pump has been rectified from the cause of the power surge.
High-tensile stainless steel shaft to handle maximum loading. It is supported by upper and lower ball bearings.
High-efficiency, squirrel caged 'dry-type' induction motor, designed to ensure energy saving operations. Housed in a water tight casing, highest insulation class is achieved by 8 hours of stator windling impregnated with varnish heat dried in industrial oven.
High grade, deep grooved, ball bearing, which is sealed-for-life type. As the bearings are permanently lubricated by grease, there is no requirement for lubricating oil.
Separate oil chamber, lubricating and cooling the mechanical seals.
Superior abrasion resistant 'double' mechanical seal is fitted as standard for the AF Series. With single spring coiled in oil chamber designed for more flexibility to accommodate misalignment, shaft deflection and break away shock loading. The mating faces at the impeller-side is SiC against SiC; whereas the motor-side is of carbon against ceramic.
An oil lip seal is mounted outside of the seal chamber to prevent solids from gathering around the mechanical seal faces.
The mechanical seal bracket is designed with 'oil elevator'. The 'oil elevator' ensures that upper mating surfaces of the mechanical seal are lubricated and cooled in the event when the oil level in the oil chamber is low. With this feature, the mechanical seal is protected, and its operating life prolonged.
