 Modular Design
Metering pumps from the ORLITA® range have a modular design and consist essentially of three assemblies:
-
Drive
-
Crank drive
-
Pump head
It is thanks to this cleverly designed system that the different types of pump head can be fitted on to any power unit. Likewise the power units, which convert the rotational movements of the motors into an oscillating stroke action for the pump head, easily work in combination with each other.
So for instance different quantities and media can be dosed with only one pump at different operating pressures. And last but not least the ORLITA® pumps are fitted with an electrical remote control facility for variable stroke adjustment and diaphragm rupture warning signal as an option, which facilitates pump operation and increases processing safety.
 Mh diaphragm metering head
Advantages
-
Safe operation: Hermetically sealed on the dosing medium side, multilayer metal diaphragm with diaphragm rupture monitoring
-
Further areas of application: Dosage capacity 0 -800 l/h per pump head, operating pressure up to 4000 bar, temperature range -60oC up to +200 oC
-
Very high dosing precision of ± 0.5%
-
Low maintenance operation: Wear-free valve-less forced after-suction
Areas of application
- Oil and gas production (on and off-shore)
- Refineries
- Chemicals and petrol chemical industry
 Features
- Performance range 0 -800 l/h per pump head, max. pressure 4000 bar.
- Temperature range -60 oC up to +200 oC
- Dosing precision ± 0.5%
- Stroke adjustment 0-100% during operation and at standstill
- Hydraulic action diaphragm head
- Metal diaphragm
- Membrane rupture monitoring
- Product area hermetically separated from the hydraulic area
- The diaphragm is moved both in the pressure stroke and suction stroke by the hydraulic medium which is displaced by the piston
- The pump head has an integrated overflow valve as well as an independently working air drain valve for the hydraulic area
- Wear-free valve-less forced after-suction of leaked hydraulic fluid guarantees optimum dosing precision.
- Depending on the nominal width and operating pressure, cone valves, globe valves or prism valves act as suction or discharge valves
- All parts coming into contact with the product are made from stainless steel
Options
-
Special work materials such as Hastelloy, zirconium, titanium, and alloy 20
-
Multilayer metal diaphragm with diaphragm rupture monitoring
-
Pump head that can be heated or cooled
-
Other designs of valve e.g. double valve etc.
-
Design according to API 675
-
Special paint finishes are possible for example for offshore applications
-
