Finish Thompson DB7

Description

Finish Thompson DB7 is used where corrosive or aggressive liquids must be transferred without the leakage risk associated with mechanical seals. The model fits flooded-suction installations in pulp and paper, chemical processing, heat exchanger and circuit board production duties, where stable chemical handling and predictable uptime are important for production and maintenance teams.The sealless magnetic-drive design isolates the pumped liquid from the motor side and removes the dynamic shaft seal from the pump. The wetted construction is available in polypropylene or PVDF, with FKM, EPDM, Simriz® or Kalrez® O-ring options and carbon, PTFE, ceramic/alumina ceramic or SiC bushing options. Ceramic, Hastelloy® C or SiC shaft options support configuration for more demanding corrosive duties. The close-coupled horizontal configuration supports compact installation and straightforward integration with suitable NEMA or IEC motor frames.Key verified data for Finish Thompson DB7 includes a flow range of 0.114-15.8 m³/h, maximum working pressure of 5.5 bar and maximum head of 10.4 m. The model has 1.5 in suction and 1.5 in discharge, and the DB family supports NPT, BSP and, on larger models, flange or union connection options. Polypropylene versions are rated up to 82°C and PVDF versions up to 104°C.For maintenance teams, the seal-less arrangement removes seal replacement from routine service planning and helps reduce leakage-related downtime risk. Replaceable wear components, practical material options and AxFlow support for selection and spare parts help keep the installed pump matched to the chemical duty and lifecycle cost expectations.

What is Finish Thompson DB7 used for?

Finish Thompson DB7 is used for flooded-suction transfer and circulation of corrosive liquids. It is relevant for pulp and paper, chemical processing, heat exchanger and circuit board production duties. AxFlow can help check whether the model fits the required duty point and liquid compatibility.

Is Finish Thompson DB7 a sealed or sealless pump?

Finish Thompson DB7 is a sealless magnetic-drive centrifugal pump. The magnetic coupling removes the need for a dynamic mechanical shaft seal. This helps reduce leakage risk and seal-maintenance requirements.

Which materials are available for Finish Thompson DB7?

The DB construction is available with polypropylene or PVDF wetted materials. O-ring, bushing and shaft options vary by model and configuration. AxFlow can help check chemical compatibility before selection.

What technical data should be checked before selecting Finish Thompson DB7?

Check flow, head, pressure, temperature, liquid chemistry, specific gravity, viscosity and connection requirements. For Finish Thompson DB7, verified data includes 0.114-15.8 m³/h, 5.5 bar and 10.4 m. Final selection should be confirmed against the duty point.

Can AxFlow support spare parts for Finish Thompson DB7?

AxFlow can support model identification, replacement-part checks and service planning for Finish Thompson DB pumps. The exact parts depend on the installed configuration and materials. Contact AxFlow with the pump model and duty details.
