Product Description

BW40-LDS Gear Pump  Overview

The Beaker & Wrench BW‑40LDS is a precision-engineered, heated positive-displacement gear pump designed for continuous, controlled feeding of high-viscosity crude and distillation feed materials under deep vacuum conditions. Built for integration with the 40L Complete Dosing System, it delivers reliable, pulsation-free flow while maintaining critical vacuum integrity, making it ideal for short-path and wiped-film distillation processes where consistent feed rates and temperature control are essential.

BW‑40LDS

Features and Benefits

  • Heated Stainless Steel Construction with Integrated Temperature Control:
    The BW‑40LDS features a corrosion-resistant 316 stainless steel pump body with an integrated heating jacket, paired with a UL-listed PID temperature controller. This design maintains optimal viscosity and prevents material solidification, ensuring smooth flow even with thick crude oils while minimizing thermal stress and contamination risks.
  • Seal‑Free Magnetic Drive for Vacuum Compatibility:
    Utilizing a magnetic coupling drive system, the pump eliminates dynamic shaft seals, preventing leaks and maintaining high vacuum integrity down to 1 Torr. This seal-free design not only eliminates common failure points but also ensures contamination-free material transfer, critical for high-purity distillation applications.
  • Adjustable Flow Rate Control for Precision Dosing:
    With a maximum speed of 70 RPM and variable speed control, the BW‑40LDS offers precise flow rate adjustment to match distillation process requirements. Operators can dial in consistent feed rates, reducing process variability and improving distillate yield and quality, eliminating the guesswork from manual feeding methods.
  • High‑Vacuum Operation and Process Continuity:
    The pump is engineered to operate under deep vacuum conditions, allowing material loading without breaking the vacuum of the distillation system. This continuous operation capability minimizes downtime between batches, significantly improving process efficiency and throughput for high-volume distillation setups.
  • Flexible Installation and System Compatibility:
    Featuring KF25 sanitary inlet and outlet ports, the BW‑40LDS is designed for seamless integration with the 40L feed flask and heated transfer lines. Its compact footprint and horizontal mounting orientation ensure compatibility with cramped lab and production environments, while the included heated feed line maintains material temperature throughout the transfer path.
  • Durable, Low‑Maintenance Design for Industrial Use:
    Built with heavy-duty components optimized for continuous use, the BW‑40LDS offers reliable performance in demanding production environments. Its robust construction and simplified maintenance requirements, combined with a 1‑year warranty against manufacturing defects, ensure long service life and minimal operational disruptions.

Applications

Applications

The Beaker & Wrench BW‑40LDS heated feed gear pump is purpose-built for vacuum distillation and continuous process systems, where precise temperature control, vacuum integrity, and consistent low‑pulsation feed are essential.
  • Short-Path Distillation Systems:
    The BW‑40LDS is the primary feed pump for mid-to-large scale short-path distillation setups, reliably metering high-viscosity crude and distillate feeds under deep vacuum conditions while maintaining precise, repeatable feed rates.
  • Wiped-Film Evaporation (WFE) & Thin-Film Distillation:
    Engineered to handle heavy, temperature-sensitive feeds in wiped-film evaporators, its heated jacket prevents material solidification and ensures uniform viscosity, supporting continuous, high-throughput processing.
  • High-Viscosity Crude & Oil Processing:
    Optimized for viscous oils, botanical extracts, and distillate streams, the pump’s variable speed control and heated design enable controlled, clog-free feeding without compromising vacuum or process stability.
  • Continuous Process Automation:
    Integrated into closed-loop distillation workflows, the BW‑40LDS eliminates manual feeding, enabling unattended, consistent operation that improves yield, reduces downtime, and supports scalable production runs.
  • Laboratory & Pilot-Scale Production:
    Its compact footprint, sanitary KF25 connections, and easy integration with standard distillation hardware make it ideal for pilot plants and production labs requiring reliable, low-maintenance feed delivery.
  • Thermally Sensitive Material Handling:
    The precision PID temperature control allows for gentle heating of heat-sensitive feeds, preventing degradation while maintaining optimal flow characteristics throughout the distillation process.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
