Centrifugal Pumps (Transfer Pumps )
From Industrial Pumps
For over 125 years CDS-John Blue Company has been committed to creating pumps that deliver uncommon performance quality and value. Our commitment to quality translates to a continual search for new technologies, materials and engineering techniques that lead to breakthroughs in pump performance and handling.
We are pleased to introduce a new impeller design ...
We are pleased to introduce a new impeller design on our 3” Self-Priming 15 HP Electric and 13 HP gasoline engine Pumps. The newly released centrifugal pump impeller has improved capacity while pressure is applied (see attached chart). For example, the new impeller will allow users to gain 75 GPM more flow at 30 psi compared to the standard impeller. At open flow (0 back pressure) users will realize a 20 GPM increase resulting in a maximum flow rate of 327 GPM. Additionally the new impeller design sustains a high shut off head of 67 psi. The new CDS-John Blue Impeller will be used on the popular 15 HP electric and 13 HP gasoline engine 3” self-priming pumps.
Through constant improvements to our centrifugal pumps, CDS-John Blue centrifugal pumps can be run dry without damaging the seal, and at a price you can afford. CDS-John Blue Company offers a 2 year unconditional warrantyon our centrifugal pumps - who else can do this?
Features:
- Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life.
- Double wet seal design provides for continuous lubrication of the seal faces. This wet seal design allows the pump to be run dry for extended periods with no damage to the mechanical seal faces.
- Closed impeller design minimizes thrust loading on the drive motor extending the life of the drive motor. Impeller wear actually increases performance.
- Extra thick cast walls provide extra strength and extend the life of the unit due to abrasion and corrosion.
