Versatile Handling for High Consistency ApplicationsThis pump accommodates a wide range of pulp consistencies, handling up to 6% fibrous stock without clogging. Its semi-open or closed impeller ensures smooth operation for both pulp and clean water. This versatility makes it ideal for stock transfer, white water circulation, and handling various industrial liquids in pulp and paper processing plants.
Durable Construction & Corrosion ResistanceBuilt with heavy-duty bearings and available in stainless steel, cast iron, or ductile iron, the pump excels in demanding industrial environments. An epoxy coating provides outstanding resistance to corrosion, making it suitable for continuous use in harsh process conditions. Its robust shaft and flexible couplings ensure stable, long-term operation.
Efficiency and Compliance with Global StandardsWith discharge pressures up to 16 bar and capacities up to 2500 m/hr, this centrifugal pump delivers high efficiency, low noise, and minimal maintenance. It complies with ISO 5199, DIN 24256, and CE standards, backed by ISO 9001:2015 quality certification. Options for automation and manual control further enhance operational flexibility.
FAQs of Pulp and Paper Stock Pump:
Q: How does the non-clogging impeller benefit pulp and paper processing?
A: The semi-open or closed, non-clogging impeller is specially designed to handle fibrous pulp stocks up to 6% consistency, significantly reducing blockage. This ensures uninterrupted transfer and processing of pulp, enhancing operational uptime and efficiency in paper manufacturing plants.
Q: What installation requirements are needed for this centrifugal process pump?
A: Installation is straightforward, as the pump comes in a horizontal, foot-mounted configuration and is supplied baseplate mounted. It requires electrical power (three-phase, 415V/380V/220V as per specification) and is designed for end-suction piping. All necessary connections for inlet/outlet and control systems are detailed in the installation manual.
Q: When should oil or grease be used for bearing lubrication?
A: The appropriate lubricanteither grease or oildepends on the operations temperature, speed, and site maintenance preferences. The heavy-duty bearings are compatible with both, but for high-temperature or high-speed operations, oil lubrication is advisable for extended service intervals.
Q: Where can this pump be applied apart from pulp stock transfer?
A: Besides pulp and paper stock handling, this pump is effective for white water circulation, clean water delivery, and transfer of industrial liquids in similar process industries. Its robust material and corrosion-resistant coating make it versatile for various liquid transfer applications.
Q: What is the typical process for startup and operation of the pump?
A: The pump can be primed manually or automatically (subject to model), and after ensuring proper priming, you can start the unit with the correct electrical supply. The direction of rotation should always be checked (clockwise from drive end). Continuous-duty design means it is suited for ongoing operation in industrial settings.
Q: How does the epoxy coating and stainless steel construction provide benefits?
A: The epoxy paint offers a strong barrier against corrosion, while the option of stainless steel shaft and components enhances resistance to both wear and chemical attack. This combination ensures reliable performance, reduces maintenance frequency, and prolongs service life in aggressive industrial environments.
Q: What certifications and protections does the pump have for quality assurance?
A: The pump is ISO 9001:2015 and CE certified, constructed as per ISO 5199 and DIN 24256 standards. It features insulation classes F or H and protection classes IP54/IP55, ensuring both electrical safety and operational reliability in compliance with international quality expectations.
