SLES Mixing & Dilution Unit

Tapflo’s SLES Mixing & Dilution System is a skid-mounted, fully automated unit designed to dilute highly concentrated SLES (70%) down to process-ready concentrations of up to 27%. Built with precision dosing, robust Stainless Steel construction, and advanced automation, the unit provides consistent, high-quality results while significantly reducing operational costs and production downtime. Equipped with a Progressive Cavity Pump for accurate handling of viscous SLES and a Centrifugal Pump for mixing and transfer, the system ensures a homogeneous, stable solution every time. With full PLC control, operators can set concentration, flow rate, and batch size, with all parameters continuously monitored and recorded.

What is SLES?

A WIDELY USED SURFACTANT RENOWNED FOR ITS FOAMING AND CLEANSING PROPERTIES

SLES (Sodium Lauryl Ether Sulphate or Sodium Laureth Sulfate) is a surfactant widely used for its excellent foaming and cleansing properties.

Found in soaps, shampoos, toothpaste, detergents, and industrial cleaners
Requires dilution to ~27% before use in most production processes

Buying pre-diluted SLES is costly and inefficient. Tapflo’s Mixing & Dilution System enables on-site dilution, cutting costs while improving flexibility and control.

Key elements of the unit include the Centrifugal and Progressive Cavity Pump, hygienic piping, flow meters and a user-friendly control panel.

Control Unit (with 7” Touchscreen)

User-friendly interface for local or remote operation. Houses the PLC, frequency inverters, and a remote access module for full automation control

Raw SLES Line

From the Progressive Cavity Pump, with a waterline that meets at the mixing point, both being fed into the Centrifugal Pump

Water Pressure Regulator

Designed to maintain stable inlet water pressure for consistent dilution and system reliability

Diaphragm Valve

Applies controlled pressure to the mixed SLES and water stream, ensuring a consistent and fully homogenised product

Centrifugal Pump

Combines raw SLES and water into a homogenous blend, operating at 6 Bar to pump the final mix

Durable Frame

Long-lasting structural integrity and corrosion resistance for harsh operating environments

Hygienic Pipework

Ensures hygienic, corrosion-resistant contact surfaces for demanding applications in personal care and cleaning industries

Flow Meters

Traces the volume of water that’s being pumped in the system for accurate batching and mixing ratios

Additive/Dosing Connection

Extra connection for injecting additives, preservatives, or for dosing water

Progressive Cavity Pump

Feeds 70% SLES with precision, handling high viscosity solutions without affecting product integrity

How It Works

SLES Mixing & Dilution Unit Process

Automated Blending Process for Precise SLES Dilution and Delivery

Step 1

Feeding

The Progressive Cavity Pump transfers concentrated 70% SLES into the mixing line

Step 2

Mixing:

A Centrifugal Pump blends SLES with water to the required concentration

Step 3

Control:

The PLC system adjusts flow rates and pump speeds based on operator settings (concentration, batch size, flow)

Step 4

Monitoring:

Flow meters, temperature/pressure sensors, and transducers continuously track process conditions

Step 5

Output:

A stable, homogeneous SLES solution at the exact concentration (27%) is discharged for immediate use
