rotary pump vendors

(OP)
Gents,
I am trying to find a vendor who can provide a rotatry PD pump for water/gasoline service. the pump spck. is 1.5 m3/h at 58 meters head. Is this the recomended pump type for such parameters? pls. let me know what vendors are there.

RE: rotary pump vendors

Hello,

I'm not sure a rotary type pump would be a good choice for gasoline/water service. I would think a diagphram type similar to that used in automotive systems would be the way to go. Fuel type pumps used in automotive service have the advantage of many years of experience pumping these fluids and probably can supply exactly what you need.

Fredb,
why you think it is not a good choice? reliability,safety or a design point of view. we do not prefer diaphragm pumps in such a hazardous service as the safety rules are very restricted in case of diaphragm failures.
what about a plunger type?

RE: rotary pump vendors

UPM,
    Check out Corken Pumps out of Oklahoma City Oklahoma and also Blackmer pumps. They are both Rotory Vane pumps. I have installed quite a few in Gasoline service and work quite well. Plunger or Triplex pumps are not recommended for this service as leakage from piston glands could be an EPA nightmare.

Thanx for the help. you think rotary will work for 1.5m3/h at 57 meters head and 0.4 meters NPSHA? this is what i have concluded so far, if you can confirm it pls.

RE: rotary pump vendors

UPM,
    Go to WWW.BLACKMER.COM under sliding vane pumps, the GX model. you can view all hydraulic and power data using adobe format. I think you will find just what you are looking for. These pumps are designed for petrolium and gasoline service.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
