Looking for that perfect fuel transfer pump unit? Look no further. We assemble these units in Omaha, Nebraska in our production facility. These fuel transfer pump units are available in either 1" transfer or 1.5" transfer capacity - flow characteristics vary drastically between the two versions.

The Dilemma & Our Solution for You

The 1" fuel transfer pump unit (DUFPU1P) will produce a flow rate of 32 GPM - at the nozzle. This is a true representation of the flow rate that the end user can expect - at the end of the plumbing system. While competitive systems will notate "max flow rate", many of them are portraying the flow rate the fuel transfer pump outputs at an open discharge. Open discharge means unrestricted flow and isn't an accurate representation of what an end user will experience, in terms of flow rate at the nozzle, once the fuel transfer pump is installed into a plumbing system. Here is a quick example of how friction loss is calculated through a plumbing system to determine flow rate - at the nozzle.

Our 1.5" fuel transfer pump unit will produce a flow rate of 60 GPM - at the nozzle. Most 12V diesel fuel transfer pumps will produce a flow rate of approximately 18-20 GPM at the nozzle. This is making the assumption the plumbing system consists of approximately 30 feet of 1" fuel transfer hose.

By making the transition from lower volume 12 Volt or 115 Volt fuel transfer pumps to the 1" DUFPU1P, end users can effectively decrease their fill times by 78%. If you choose to bump up to the, larger, DUFPU1.5P you can decrease fill times by 233%.

That is a serious cost savings when looking at the operational expenses of paying operators to wait around while large equipment fuel tanks are being filled. If you are able to save 15 minutes of fill time, per fill, how much money does that save you in a week? How about a month or a year?

Reduce waste, reduce cost, and increase efficiencies of your operation. Bigger, faster, stronger is the name of the game and these Dultmeier fuel transfer pump units will help you achieve that status.

Either fuel pump transfer unit option, that we manufacture, is fitted with the MP Pumps PetrolMaxx 2" self priming diesel fuel transfer pump. These fuel pump transfer units are designed to safely handle diesel or bio-diesel fuels and significantly reduce operating expenses and improve the efficiency of your operation.

Product Demonstration

Our, larger volume, DUFPU1.5P boasts the following features:

• CRX 6.5 HP manual start engine with C.A.R.B. rating.
• MP PetrolMaxx 2" self-priming cast iron pump with Type 21 Viton® mechanical seal designed for diesel fuel
• Hannay spring rewind hose reel
• Husky high flow automatic nozzle with swivel.
• Cimtek 1-1/2" 60 GPM fuel filter with 2-30 micron Hydrosorb elements,
• 38' of 1-1/2" fuel transfer hose and Husky 1690 1-1/2" high flow automatic nozzle.
• Mounted on steel base plate (powder-coat finish)

How do I match my pump rotation? This is a commonality that we address on almost a daily basis but many people do not understand how to accomplish this task. At Dultmeier Sales we are glad to help out and explain over the phone or you can get your answer right here:

First off, let's address how we look at a pump - the direction of rotation is always determined when FACING THE SHAFT. Centrifugal pumps are available in two options, either Counter Clockwise (CCW) or Clockwise (CW). To match the pump shaft with a drive shaft we always MATCH THE OPPOSITE ROTATION.

A gasoline engine will match up to a CW drive centrifugal pump. A front tractor crankshaft PTO rotates in CCW direction and therefore must be mated to a CW centrifugal pump. While a rear PTO shaft drive (CW rotation) application must be mated to a CCW pump. This is somewhat counter intuitive to those new to the concept but a "standard drive" centrifugal pump will actually be CCW rotation. Therefore, a "reverse" drive pump is actually CW.

Confused yet? Check out Ace Pumps description for further clarification along with pictures. A common symptom of not properly matching shaft rotation is no pressure generation by the pump. We receive calls from people describing that their brand new pump won't create any pressure and immediately point at the pump as the culprit. More often than not, it's not the pump's fault - generally there is an application error or human error causing the issue. In the scenario described above the first thing to confirm is that we have the correct pump shaft rotation matched with drive shaft choice. More often than not, this is the root of the headache. If you are still struggling give us a buzz and we will be happy to lend a hand.
