Enduramaxx 400 Litre Chemical Dosing Tank
Product Overview
The Enduramaxx 400 Litre Chemical Dosing Tank is a vertical, rotationally moulded tank designed for storing and mixing chemicals, reagents and other compatible liquids.
It is manufactured from MDPE (medium-density polyethylene) using a food-grade polymer rated to 1.5 specific gravity (SG). The tank is UV stabilised and moulded as a single piece, eliminating seams and welds that could otherwise create weak points

Chemical Resistance
The tank is manufactured from MDPE, which Tanks Direct describes as having good chemical-resistance capabilities.
It is intended to be compatible with a wide range of chemicals and reagents, but chemical compatibility should be confirmed for the specific substance being stored. Tanks Direct specifically offers to check compatibility using the chemical's MSDS/SDS information.
This is particularly important for aggressive chemicals, oxidising agents or concentrated solutions.
Graduated Level Scale
The tank incorporates a graduated scale for monitoring the quantity of liquid inside.
The natural version allows the liquid level to be viewed through the tank. Other options are available for black tanks, although these need to be quoted in advance.
Lid & Equipment Installation
The tank has a 240 mm lid opening and a stepped design.
The manufacturer states that this arrangement allows the installation of equipment such as:
- Mixers
- Pumps
- Dosing equipment
- Other processing equipment
This makes the tank more suitable for active dosing and mixing processes than a basic storage tank.

- Water treatment
- Water purification

Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
