The Flux F425 Series Electric Barrel Pump can empty up to 99.98% of the barrel contents, preventing waste and limiting fluid spillage, which makes it ideal for handling high grade/high-value fluids, for example, in the cosmetics industry. This chemical barrel pump comes complete with a flow backstop valve at the pump inlet that can be closed before removing the pump from the container. This unique feature of the chemical transfer pump makes it ideal for handling high value fluids as it ensures any excess liquid stays in the tube when moving the pump from drum to drum to prevent wastes or unnecessary expenditures.

Suitable to transfer low viscosity expensive or dangerous liquids up to 1200cP, this Flux drum pump can be used with barrels, drums or IBC's. The F425 chemical transfer pump is also lightweight and easy to move, dismantle and clean, meaning it can be used for multiple pumping applications. This electric barrel pump is available in with FFKM o-rings for handling aggressive liquids and in a variety of materials, including stainless steel and models with ATEX certificate.

Features of the F 425 Flux Drum Pump:

  • Heavy duty, electric barrel pump
  • Designed for up to 99.98% emptying of drums and IBCs
  • Suitable for use with low viscosity fluids up to 1200cP
  • Flow back stop valve
  • Optimum barrel emptying due to unique impellor design
  • Easily dismantled for cleaning
  • Version in stainless steel is tested and certified according to ATEX-Directive 94/9/EC, category 1/2, for use in Zone 0 – EC-Type-Examination Certificate No. PTB 00 ATEX 4110 X
  • Variety of motor options available including brushless motors, commutator motors, air motors and three-phase gear motors

This Flux pump is a perfect pumping solution for transferring low viscosity high value or dangerous fluids from drum or IBC. The chemical transfer pump has a compact design and provide a pulsation-free transfers of fluids.

  • High-quality barrel pump – Flux pumps are well known German-made barrel pumps that have been in the market for over 70 years.
  • Quickly disassembled for cleaning – The F425 electric drum pump for chemicals can be quickly and easily taken apart for cleaning, making it a perfect pumping solution for many industrial applications.
  • Optimal barrel emptying – This Flux pump can empty up to 99.98% of the barrel contents, providing optimal use of fluid and preventing waste.
  • No fluid spillage – F425 has a unique a flow backstop valve that ensures any excess liquid stays in the tube when moving the pump from drum to drum to prevent spills and waste.

The Flux F425 drum pump is designed for transferring light liquids, including chemicals, acids and oil up to 1200 cP. The chemical pump is ideal for use with expensive or dangerous liquids where spills should be avoided.

  • Acids such as hydrochloric acid, boric acid, sulfuric acid, citric acid
  • Petroleum, diesel, heating oil, hydraulic oil, engine oil
  • Gasoline, formic acid (as from 85 %), ethylene glycol

The Flux F425 Series Drum Pumps are available with the following material options:

PPSTAINLESS STEEL 316 L/316 Ti (S)

FAQs

Put most simply, a barrel pump, is a pump connected to an immersion tube that sits within the drum with its motor located outside of the container. The pump draws up the fluid through its immersion tube and is then dispensed via a hose or pipe that is connected to its outlet.

If you have a 1000 litre IBC you will require a 1200mm tube, a 205 litre drum requires a 1000mm and if you have a smaller container 700mm and shorter tubes are available. For larger containers we can offer longer tube sets on specification

If your fluid is prone to crystallisation, then you can use the F310 or F430 models as the pump bearings are protected from wear.

The F425 model is capable of emptying 99.98% of a container's contents. This drum pump is generally selected when the liquid is particularly valuable to minimise waste.

The F426 model is capable of both mixing and pumping the liquid within the container, which is a lower cost solution when compared to a separate mixer and pump.

For liquids with a flashpoint below 50°C, we offer our Stainless Steel F400 models and Viscopower series with ATEX approved motors or Viscoflux Lite EX.

Our range includes both FDA and 3A approved hygienic models. When the viscosity is >1200cP we offer the sanitary Viscopower F570 and F580 models and the Viscoflux Mobile. If <1200cP we typically select the F427, or the F430 food grade version when pumping alcohols or foodstuff with solids.

If you are pumping one liquid or very similar liquids, you can use the F314 or F424 seal-less models, if you are pumping multiple diferent liquids or where cross contamination is not desirable use the F310 or F430 drum pumps.

To ensure you get the correct Flux spare parts, we need to identify the exact Flux pump model you have. Please provide the model and serial number found on the pump name plate.

Castle Pumps can supply all Flux pump parts detailed on the spare parts list including motor, o-ring, shaft seal, impeller, inner and outer tube worldwide.

If you are pumping one liquid or very similar liquids, you can use the F314 or F424 seal-less models provided that the materials are compatible, if you are pumping multiple diferent liquids or where cross contamination is not desirable use the F310 or F430 drum pumps.

The general rule of thumb is that for low-medium duty applications where viscosity is <250cP the F300 is sufficient. For heavy duty applications, flammable liquids and viscosities of <1200cP choose the F400. For shear sensitive fluids or viscosities that exceed 1200cP then the Viscpower is required. Upon disclosure of your application, we can confirm the best solution.

All Flux barrel and IBC pump models are available with additional accessories that we can supply as a kit should you need delivery hose, a trigger nozzle, valves, flow meter and any other fittings.
