Fluoroplastic Pipeline Pump -

A vertical, fluoroplastic-lined pipeline pump engineered for handling aggressive and corrosive liquids. Wet-end components and wetted parts are formed from high-temperature molded PTFE (polytetrafluoroethylene), delivering chemical resistance superior to conventional metal-lined designs and extending service life in demanding process environments.

Key features and benefits:

• Corrosion-resistant wetted parts: High-temperature molded PTFE lining protects the pump casing and flow path from strong acids, alkalis and other corrosives.
• Close-coupled direct-drive design: The impeller is directly connected to the motor shaft (short bracket close-couple), eliminating a separate bearing housing and coupling to reduce mechanical energy loss, improve overall efficiency and lower noise.
• Compact vertical footprint: Vertical pipeline arrangement with matching inlet and outlet diameters — no need for pipe-diameter transitions. Multiple units can be connected in series to increase head while saving floor space.
• Wide operating temperature range: Suitable for process temperatures from -20°C to 150°C.
• Robust shaft and sealing arrangement: Impeller and shaft at the mechanical-seal area are an integrated assembly; torque is transmitted to the motor via a taper fit. The shaft seal uses a WB2 external corrugated-pipe mechanical seal for reliable leakage control in corrosive services.
• Motor configuration: Supplied with a specially designed hollow motor shaft — vertical V1 type hollow-shaft outdoor motor, running at 2,900 rpm.

Typical applications:

• Petroleum, chemical processing and petrochemicals
• Metallurgy and power generation
• Flue-gas desulfurization and dust-removal systems
• Pulp & paper and synthetic fiber production
• Food, pharmaceutical and specialty chemical transfer where corrosion resistance is required

Notes on construction and maintenance:

• The close-coupled pump uses a threaded pull rod to lock the impeller shaft to the motor shaft for compact assembly and straightforward servicing.
• The design minimizes rotating parts and coupling losses, reducing maintenance points and improving efficiency compared with long-coupled arrangements.

For purchasing and engineering evaluation, typical data to confirm with supplier: connection size, flow and head range for the GF/GDF series model selected, specific PTFE lining thickness and compatibility with your process fluid, mechanical seal material options, and motor enclosure/insulation class for outdoor installation.
