Prime-GPT was initially founded as Trinity Pumpenwerk GmbH and later renamed Trinity-HDD. The strategy was to sell and service American made pumping equipment. Our focus was to help international customers receive better after-sales service and easier access to critical spare parts. Simply put, the idea was to establish ourselves as distributors of pumps & spare parts and conduct business according to local customs.
We began and are still purchasing from the well-known pump manufacturers in the industry, that would grant us distributor pricing. Later we began to build important pump parts for pumps which are obsolete and parts which are very rare.
Needing capital to fuel our rapid growth, the decision was made to sell shares of TRINITY Pumpenwerk to Prime Drilling GmbH. Within the framework of this re-organization Trinity Pumpenwerk GmbH became an official division of Prime Drilling GmbH and was renamed TRINITY-HDD.


To reflect the long-standing excellent cooperation with Prime Drilling in the company´ s name TRINITY-HDD was renamed Prime-GPT (German Pump Technologie) GmbH. 90% of our market contains HDD related customers. The other 10% of our market is Vertical Drilling- (Geothermical, Oil & Gas) and Industrial applications. Therefore our slogan remains …keeps your fluid moving!




Today Prime-GPT and PRIME DRILLING work together as designers, developers and manufacturers of state of the art pumping equipment and pump consumables. We build a line of reciprocating piston pumps and packages designed specifically for the HDD industry. The maximum capacities of these pumps exceed 4000 LPM (1060 GPM) and are rated up to 110 bar (1600 psi). We are investing heavily into advanced software and machinery that allows us to deliver products that last longer and are more economical. There is a lot more to tell and we hope we get a chance to show you what we can do for you!
