What Is a Hydraulic Reservoir Tank?
A hydraulic reservoir stores and conditions the hydraulic fluid that powers your system. It’s not just a container — a well-engineered reservoir controls heat, separates contaminants, and ensures consistent fluid delivery under load.
At Engineered Welding, every tank is built from your drawing or spec sheet — not a stock unit modified to fit. We fabricate from mild steel, stainless steel, and aluminum, with custom port locations, baffles, drains, breathers, and mounting options built in from the start.
Whether you need a single prototype or production quantities, we turn around quotes fast and build to tight tolerances with full weld quality and leak testing before shipment.

Frequently Asked Questions
Can you build a tank from my drawing or sample?
Yes — that’s our primary business. Send us a CAD file, PDF, DXF, or physical sample and we’ll quote from it directly. We don’t require you to adapt to a stock design.
What materials do you work with?
Mild steel, stainless steel, and aluminum. Material choice depends on your fluid type, operating environment, and weight requirements — we’ll help you select the right one.
What’s your typical lead time?
Lead times vary by complexity and quantity. Contact us with your drawing and we’ll give you a specific timeline with your quote. We work with customers who need both prototype speed and production scheduling.
Do you do leak testing?
Yes. Every tank is tested before it ships. We don’t send product out the door that hasn’t been verified — your system reliability depends on it.
Do you ship outside Iowa?
Yes — we ship nationwide. We have customers across the Midwest and beyond. Contact us to discuss freight options for your order.
