Hydraulic Tank Questions
How do I size the reservoir for my system?
For open circuits, typically 3–5× pump flow plus ~10% air space;
Closed circuits can be smaller.
Validate versus duty cycle, heat load, and de‑aeration.
Which tank materials does Hydrath offer and how to choose?
Steel, stainless, aluminum, and plastic (PP).
Choose by environment/performance: steel general duty;
- stainless for corrosion/chemicals;
- aluminum for lightweight and thermal conductivity;
- PP for cost‑effective, non‑corrosive fluids and moderate temps.
What operating temperatures are typical by material?
- Aluminum: −30 to +120°C;
- steel/stainless: −20 to +120°C;
- PP:−10 to +80°C.
Depends on fluid, seals/paint, and duty cycle.
What port standards are supported?
NPT, BSPP/G, ISO metric (ISO 9974 style); adapters available on request.
What mounting styles are available?
Side/top/foot mounts; mobile bracket kits; custom footprints and hole patterns.
How do I reduce aeration and foaming?
Use return diffusers, baffles, low‑velocity returns, adequate volume/dwell time, proper fluid level;
Avoid suction near return splash.
Typical capacity range?
Catalogue typically 2–150 L;
larger/special geometries on request.
What information should I provide for a Hydrath quote?
Pump flow/duty cycle, ambient/heat load, fluid type/viscosity, material preference, porting standard, footprint/mounting constraints, accessories list.
