Process Pump

With very compact design these pumps provide zero emission operation by using hermetically seals within the pump which provides prevention of leakage to atmosphere during operation that enables use of the pump in hazardous areas.<br>Typical operations include pumping of methanol, jet fuel, ethanol, diesel oil, crude oil etc.<br>Some typical applications like Fatty alcohol process, LDPE, Wet oxidation, Nonwoven fabrics use these pumps.

HDP 755 Compact construction Compact construction HDP 485 The integral speed reducer with twin helical gears arranged in a herringbone configuration ensures smooth running and even power transmission without axially loading the bearings. Hammelmann pumps produce maximum performance from a minimal footprint which is the result of combining a compact integral speed reduction gear end with the concept of a vertical configuration. HDP 365 HDP 255 Sealing systems Sealing systems HDP 175 HDP 125 The seal designs which are absolutely unique to Hammelmann enable safe, reliable, continuous duty operation at pressures up to 3800 bar. The choice of high pressure seal system depends upon the pump’s application. Labyrinth seal The high pressure seal is formed within the minute cylindrical gap between the plunger and the labyrinth insert. The medium pressure is continuously reduced along the sealing surface. A minimum amount of high pressure leakage serves as lubricant and is returned to the pump suction chamber. Packed seal PTFE/Graphite rings maintain the high pressure seal while plunger guidance is provided by a separate bush.

Conical/Plate valve The suction valve is in disc form plate design and the discharge valve is conical. Both seat to a one piece component.

The intermediate chamber of the pump can be outfitted with gas tight covers which provide a seal to atmosphere. The chamber is then charged with inert gas. OUT Packed seal Labyrinth seal Low pressure seal packs The suction chamber is sealed by combining spring tensioned PTFE rings either side of a lantern ring which is used either for flushing, cooling or lubricating the seal (optional).
