Pump Case – Field Demonstration Video

In this field demonstration of the pump case PC-2025-1000UV, WeissExplorers presents a quick overview and setup of a portable and modular multi-stage water filtration system.

This system was developed for our own overlanding use, with the goal of reliably producing clean and safe drinking water in the field. It is designed with a strong focus on durability, repairability, and carefully selected materials. The system is open-source, and the full build guide is available for download.

Protecting our health means relying on a safe and durable filtration system — one that doesn’t add its own problems through cheap plastic components. That’s why I build my systems primarily from stainless steel and premium-grade parts, ensuring that every drop of water is as pure and safe as it should be.

Building a portable water filter and pump case was a great project where I could use my experience from plant engineering for water management for a real outdoor solution that would be very handy for overlanding.

Having a portable, rugged and capable tool to cope with many different situations and to produce clean and fresh drinking water was the main goal in developing this pump case.

What can be filtered with the Pump Case?

Inside the pump case we use a activated carbon filter, a hollow fibre membrane filter with a pore size of 0.1 µm and a UV unit. The following compounds can be filtered with this setup effectively:

• Micro plastics
• Odors
• Bacteria
• Viruses
• Sediments
• Asbestos
• Yeast
• Pollen
• Heavy metals
• Pesticides
• PFAS*
• Pharmaceutical residues*

Standard activated carbon significantly reduces PFAS and pharmaceutical residues, but not completely. For 100% removal, special ion exchangers or reverse osmosis would be required.

Having a multi-stage filtration system is the optimal way to protect your health. Learn more about bacteria, viruses, protozoa and other various pathogens here.
