To ensure that only pure uncontaminated product is drawn off from a storage tank, it is important that the product is drawn from a high level, just below the surface of the liquid. Floating suctions units move up and down as the liquid level change, thus preventing sediment or water being drawn off.

This is possible because Swivel joints are fitted which guarantee smooth leak free articulation.
Materials of construction are carefully selected for the specific product requirements

Floating Suctions compared with permanently fixed bleeding nozzles have the following advantages:
- The product always is transferred in a defined distance under the liquid level
- Contamination dirt/sediments / solid particles and heavy fluids remain on the tank bottom
- Therefore constant quality independent from liquid level

Emco Wheaton Floating Suctions offer:
- ease of steering and long lifetime due to ball bearing of swivel joints
- easy mounting due to internal swivel joint flanging
- robustness against pressure conditions (pressure variations) in tank and tube
- minimal vortex formation through optimised inlet with anti-vortex suction
- pressure-proof floats

Design:
- internally fixed at unloading tube
- consisting of an elbow-tube-system with a suction opening which is held close to the liquid
level by a float drawing
- various designs, depending on the tank dimensions and types

Materials depending on the design and requirements:
- aluminium, carbon steel, stainless steel

Seals in accordance to the fluid:
- Buna N, Viton, PTFE
- special designs are possible on request, e.g.
