safety meets versatility
At this year's ACHEMA in Frankfurt, June 11 to 15, 2018, ProMinent will present the extended product range of the Orlita® Evolution series at its stand J94 in hall 8. The Evolution 1 to 4 ranges, which were previously only available with a stainless steel metering unit, can now also be equipped with metering units made of PVC and PVDF.
This extends the potential applications of the pumps, while at the same time reducing costs – particularly for applications with aggressive media. In addition to this, ProMinent added the rugged and precise EP1 and EP2 piston metering pumps to their line of hydraulic diaphragm metering pumps.
All Evolution versions with stainless steel and plastic metering unit, as well as those with a piston dispensing head, have a modular structure. They can be flexibly designed as single-pump or multi-pump versions. With multi-pump systems, up to four metering units can be combined, including units with different delivery capacities. The special feature is the position-independent arrangement of the drives – with both vertical and horizontal installation possible. Seven freely selectable and different gear reductions provide maximum flexibility. The high-performance plunger metering pumps Orlita® Evolution EP1 and EP2 enables precise pump capacities even at maximum pressure and temperatures of up to + 200 °C.
A key advantage of the new plastic metering units made of PVC and PVDF is their high resistance to aggressive chemicals. When equipped with these, the Orlita® Evolution is an affordable alternative to pumps with dispensing heads made of resistant materials, such as Hastelloy. Until now, these highly corrosion-resistant nickel alloys needed a high molybdenum content, as they are also resistant to aggressive media.
As extremely robust hydraulic diaphragm metering pumps, the Orlita® Evolution models meet the strictest safety requirements. Among other things, they excel through their PTFE multi-layer safety diaphragm with integrated diaphragm rupture warning/indicator, as well as their diaphragm position control. All pumps are designed in accordance with API 675. With a large variety of drive versions, use in Ex Zone 1 and Zone 2 is even permitted with ATEX approval.
