The biggest advantage with the hose pumps over the roller pumps is the high operating pressure of up to 16 bar. With rollers, max pressure can arrive up to 12 bar (170 psi) without any problem. If the high operating pressure is not required, a tubing pump is a better option than a hose pump if the pumped medium is not abrasive.
This pump type operates without a foot valve and without an evacuation device on the suction side. The pump has to be primed with the fluid to be handled prior to commissioning. Two-phase mixture is pumped until the suction line has been evacuated and the fluid level has been pushed into the front suction intake chamber by atmospheric pressure.
The toothpaste pump, also known as a toothpaste pump dispenser, is a device used to contain and dispense toothpaste, akin to a tube. An automatic toothpaste dispenser is a self-starting way to dispense toothpaste.
