What is CQB-F Fluoroplastic Lined Magnetic Drive Pump (Without Baseplate)？

The CQB-F fluoroplastic lined magnetic drive pump (without baseplate) is industrial equipment manufactured using materials such as fluoroplastic alloy F46/PFA. Operating as a leak-free magnetic drive pump, it achieves non-contact torque transmission through permanent magnet coupling. When the electric motor rotates the outer magnetic steel assembly, magnetic flux penetrates the isolation sleeve to drive the inner magnetic assembly and impeller synchronously. Designed as an efficient close coupled pump, this compact chemical transfer pump is applied across petrochemical, pharmaceutical, and electroplating industries to convey highly corrosive media including acids, alkalis, and oxidants.

Applications & Features

Wide Applications:Thismagnetic drive pump is widely utilized across industries such as petrochemicals, acid and alkali production, non-ferrous metal metallurgy, automotive pickling processes, rare earth separation, pesticides, dyes, pharmaceuticals, papermaking, electroplating, and radio manufacturing. Functioning as a high-efficiency close coupled pump, it serves as a dependable chemical transfer pump for aggressive fluids without risk of external environmental contamination.

Product Features:

Zero Leakage & High Efficiency: Eliminates conventional shaft seals by utilizing magnetic coupling to guarantee zero leakage. Its close coupled pump design removes rolling bearing friction losses to ensure quiet, energy-efficient operation.
Compact & Flexible Configuration: Features a reduced footprint for easy installation in tight spaces. This magnetic drive pump allows flexible power pairing and configuration to match actual working conditions cost-effectively.
Premium Materials: Built with a protective metal outer casing internally lined with fluoroplastics and composite materials, ensuring this chemical transfer pump delivers high and low-temperature resistance, anti-aging durability, and broad corrosion resistance without toxic chemical decomposition.
Drive Device: Utilizes a magnetic coupling mounted directly onto the motor shaft to maintain a safe, compact, and energy-saving close coupled pumpassembly.

Q1: What is the main structural difference and advantage of the version without baseplate compared to the baseplate version?

Saves floor space and installation cost. The model without baseplate features a direct-mounted, compact design. It allows engineers to integrate the pump directly into tight machinery skids or custom mounting plates without adding extra baseplate weight and bulk.

Q2: Does the lack of a common baseplate affect alignment between the motor and the pump chamber?

No. The pump uses a close-coupled rigid frame structure. The pump casing, magnetic bracket, and motor are factory-aligned via precision machined flanges, ensuring stable coaxial operation without manual shaft alignment on site.

Q3: How do you prevent piping stress from damaging the fluoroplastic lining on this base-less version?

Use flexible expansion joints (bellows). Because the pump relies on its own mounting feet, suction and discharge pipe loads should be anchored independently to external pipe supports, with flexible joints installed at the flanges to absorb pipeline thermal expansion and vibration.

Q4: Is this model lighter for international freight shipping costs?

Yes. Eliminating the heavy cast-iron baseplate significantly reduces the overall gross weight and packaging volume, making air/sea freight costs noticeably lower for overseas shipments.
