WA/WD – Standard Hopper Pump
The ‘W’ Series pump is a Special adaptation of the standard Progressive Cavity pumps, This pump design is modified as such with a Wide-throat Suction Inlet which allows the media to enter the suction housing with ease and avoids clogging, Additionally the pump is equipped with a Screw conveyor type of arrangement which pushes the liquid forward with aa slight change in design. These Pumps are specially used for applications where the media is highly viscous & a higher concentration of solids.
Capacity: 0.1–150 m³/h
Pressure: ≤ 36 bar
Optimum product conveyance
Conveyance of the optimal flow rate to the downstream rotating unit by compressing the medium in the compression zone
Variable
Available in Close-coupled design with directly flanged-on drive system, or as a variant with bareshaft variant.
Robust
Heavy Duty Cardan Joint offers best value by increasing the life cycle of parts.
Fits All
Available with various rotor/stator geometries and a wide range of different shaft seals – tailored to suit any conveying process
- Discharge Port:
Available with Gauge Connection, Flange Connections conforming to ISO, DIN & ANSI standards.
- Rotor:
Wear resistant and corrosion-resistant materials. Optionally with hard surface treatment.
- Conventional Geometry : With Shorter Pitches the geometry is for high Pressure applications
- Extended Geometry: With a Small rotor diameter and a long pitch, the Extended geometry attains lower surface velocities and extends the service life due to its large sealing line.
- Stator:
The seal on both ends is molded as an integral part of the elastomeric stator.
- Suction Housing:
Rectangular design, hopper length customized to meet special applications. Compression zone
Flanges at both ends for quick disassembly when replacing the rotor, hand hole on request..
- Augar Type Connecting Rod:
Connecting rod with screw conveyor with progressive pitch for power transmission and conveying of viscous products
- Robust Cardan Type Joint
Heavy Duty, Robust , Long Lasting Cardan Type Universal Joint , it can handle more load due to its inherent design. These joints offer a longer service life than the conventional Pin joint.
- Yoke Shaft
Connects the drive shaft to the joint. With gland packing the plug-in shaft is used as a shaft protection sleeve. Upon request, it is available with wear resistant coating
- Shaft Sealing:
Available in Gland Packing and also with Flushing lantern Ring , Single Mechanical seal as well as Double Mechanical seals
- Drives & Drive Arrangements:
Available in both Bareshaft Drive Configuration – WACB series, as well as Close Coupled Drive Configuration WDCB Series .
Geared motors, variable speed drives or frequency controlled motors are offered, Also offered are Drive shrouds made of Stainless steel.
- Dry Run Protection :
Dry Run protection monitors the temperature of the stator and shots the pump down when the limit value is reached to protect the pump from dry running,
- Overpressure Protection :
The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.
- Seal Support Systems:
We offer seal Flush, Quench, Barrier type support systems. barrier type systems protects the shaft sealing by selectively supplying barrier liquid. Also available with flow meter on request - Retensioning Device:
With this device, a worn stator can be evenly readjusted at several points so that the clamping between the rotor and stator is once again optimal and the pump performance increases.
- Standard Baseplate:
Suited baseplate for mounting with geared motor, for standard applications , specialized features available as per custom requirements
- Sealing Options
- Standard Gland Packing
- Multiple Acting Mechanical Seal
Mechanical seals arranged in a row. Available in “back-to-back”, “face-to-face” or “tandem” sequence - Cartridge Mechanical Seal
Ready-to-install pre-assembled units with supply connections and attachment brackets for quick replacementUniversal choice for sealing the Gland area in the pump. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device. - Single Acting Mechanical Seal
Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing of liquid from the Gland area in the pump .
