CP-5 Constant Pressure Cylinder

The Welker CP-5 Constant Pressure Cylinder is designed to contain and transfer accurate samples or calibration standards for laboratory analysis. 

Contents are maintained under full pipeline pressure by pre-charging the CP-5 with an inert gas or pipeline gas. Filling a pre-charged cylinder protects against phase change and maintains the sample's integrity by collecting sample at full line pressure. End caps with valves, gauges, and relieving devices enable the cylinder pressure to be controlled and monitored at all times. 

The internal floating piston plays a key role in volume indication and contamination prevention. As the cylinder is filled and the piston moves inside the cylinder, the operator can monitor the product level by referring to the graduated scale on magnetic indicator models or the indicator rod on solid indicator models. 

As the cylinder is emptied, the piston wipes the cylinder walls clean and forces any air and/or contaminants from the cylinder, preventing cross-contamination between samples. 

The optional internal Gravity Mixer™ is recommended for products thatstratify. Repeatedly inverting the CP-5 with Gravity Mixer™ evenly distributes the entire sample inside the cylinder to provide a uniform mix prior to analysis. 

The optional vortex mixer is recommended for high viscosity products and products thatstratify. The sample is mixed manually by pushing down and pulling up on the T-handle of the mixing rod. This manual mixing action creates a vortex or spiral movement in the sample. 

The vortex causes a pressure drop at the center of the cylinder, which pulls the stratified product toward the middle, thoroughly mixing the entire sample inside the cylinder to provide a uniform mix prior to analysis. 

Welker may custom design the CP-5 to suit the particular application and specifications of each customer.
