The Krogh Carver 855 pump is a cornerstone of vacuum filtration in pulp and paper production, functioning as a vacuum pump with a capacity of up to 700 gallons per minute and vacuum levels reaching 26 inches of mercury. It efficiently dewaters pulp slurries during stock preparation, pulling water from fibrous mixtures to prepare pulp for pressing and drying stages, with a low NPSH requirement (typically 3-5 feet) that ensures stable operation even under high-vacuum conditions. Integrated with disc filters or savealls, it excels in fiber recovery, capturing up to 90% of fine fibers from white water streams, enhancing pulp yield and reducing raw material costs. The Wilfley 2AG and 3AG pumps handle abrasive pulp slurries, transferring thick, fibrous mixtures through pipelines with capacities up to 1,000 GPM, while the Wilfley 3A7 supports slurry movement and wastewater processing from bleaching and washing stages, managing flows up to 800 GPM. These applications ensure seamless production—from refining to effluent management—maintaining paper quality consistency and operational uptime across the mill.

Our aftermarket parts for the Krogh Carver 855 and Wilfley 2AG, 3AG, and 3A7 pumps are crafted from advanced materials like CD4MCuN and Duplex Stainless Steel, providing exceptional resistance to the corrosive and abrasive conditions of pulp processing. The Carver 855’s vacuum filtration capabilities extend pump life by up to 25% over OEM parts, thanks to its robust semi-open impeller design and ability to resume pumping after flow interruptions—a critical advantage in maintaining filtration efficiency under variable pulp loads. Precision engineering with 3D scanning technology ensures tolerances as tight as 0.001 inches, guaranteeing a perfect fit and optimal performance for both vacuum and slurry applications. Priced at half the cost of OEM components, our solutions reduce maintenance frequency by up to 30%, cut downtime, and improve fiber recovery rates, boosting throughput consistency and yielding operational savings of 15-20% annually. This blend of longevity, reliability, and affordability offers mills a competitive edge in a demanding industry.

KLD Pumps supports pulp and paper mills across key U.S. regions, including Tennessee, Georgia, and the Pacific Northwest, delivering tailored solutions to address regional challenges. In Tennessee, where major producers like International Paper operate high-volume facilities, the Krogh Carver 855 enhances vacuum filtration under continuous production demands, ensuring reliable dewatering and fiber recovery with suction power that maintains pulp quality for large-scale paper manufacturing. In Georgia, home to pulp processors like Georgia-Pacific, our Wilfley 2AG and 3AG pumps manage dense, fibrous slurries in humid, wear-intensive conditions, while the Carver 855 optimizes filtration efficiency to support high-throughput pulp production. In the Pacific Northwest, a leader in sustainable pulp production, our parts streamline water-intensive processes, reducing wastewater volume by up to 10% and aligning with eco-friendly goals through efficient effluent management. By meeting these diverse needs—high throughput, abrasion resistance, and sustainability—KLD Pumps ensures consistent performance and long-term value for pulp and paper clients nationwide.

KLD Pumps provides aftermarket parts to a wide range of leading pulp and paper manufacturers across the U.S., supporting their critical vacuum filtration and slurry handling needs.
