The self-priming centrifugal, a specialized end suction pump design, creates a vacuum at the impeller eye to continuously remove air from the suction line.
Hydra-Cell Q155 Series pumps can operate with a closed or blocked suction line and run dry indefinitely without damage, eliminating downtime and repair costs.
In addition to zero leakage, the pumps can run dry without damage, will operate with a closed or blocked suction line, and can pump abrasive fluids effectively.
The suction line housing is placed higher on the pump, allowing the empeller and mechanical seal to be covered with water at all times, eliminating the need to reprime the pump and protecting the seal from running dry.
The Vortex pump technique developed by Wemco is based on the principle of a whirlpool: a vortex is created by the rotating, recessed impeller, extended into the suction line, drawing the liquid solids into the pump and then quickly through the discharge, whilst minimising the fluid / solids contact with the impeller and volute.
After this step the cleaned bilge water with less then 15 ppm of oil is lead back through a three-way valve into the present OWS suction line and is pumped overboard through the existing OWS and controlled by the present oil content metre.
In the case of the diabatic capillary tube, and the compressor-suction line being colder, the heat transfer from the capillary tube to the suction line causes the liquid length to increase, thereby causing the refrigerant mass flow rate through the capillary tube to increase.
In a diabatic capillary tube, the capillary tube is bonded with the cold compressor suction line to form a counter flow heat exchanger.
Return line design will keep a constant line velocity throughout the entire system, while suction line design will focus on slowing the velocity as the flow approaches the suction outlet.
Ensure the suction line insulation is continuous and serviceable.
