ORLITA® Mf Hydraulic Diaphragm Metering pump

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, work smoothly together.

So for instance the different quantities and media can be dosed with only one pump at different working 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.

Mf Diaphragm liquid end

Advantages

• Reliable operation: Hermetically sealed on the dosing medium side, PTFE double diaphragm with diaphragm rupture monitoring
• Further areas of application: Discharge capacity 0 – 30,000 l/h per pump head, operating pressure up to 700 bar, temperature range –40°C up to +160°C
• Exceptionally high suction up to 8 m
• Very high dosing precision of ± 0.5%
• Low maintenance operation: No-wear valveless forced after-suction, cone valves as suction or discharge valves with low wear and self-cleaning.

Areas of application

• Oil and gas production (on and off-shore)
• Refineries
• Chemicals and petrol chemical industry
• Pharmaceutical and cosmetics
• Production of food
• Packaging industry (filling pumps)

Features

• Performance range 0 – 30,000 l/h per pump head, max. pressure 700 bar.
• Temperature range - 40 °C up to + 160 °C
• Suction lift up to 8 m
• Dosing precision ± 0.5%
• Stroke adjustment 0-100% during operation and at standstill
• Hydraulic action diaphragm head
• PTFE double diaphragm
• Membrane rupture monitoring
• Product area hermetically separated from the hydraulic area
• High suction performance: The diaphragm is moved during the pressure stroke action solely by the hydraulic fluid and supported if necessary during the suction action by a mechanical coupling.
• The pump head has an integrated overflow valve as well as an independently working air drain valve for the hydraulic area
• Wear-free valveless forced after-suction of leaked hydraulic fluid guarantees optimum dosing precision.
• Cone valves as suction or discharge valves with low wear, good self-cleaning and low pressure loss (NPSHR)
• All parts that come into contact with the product are made from stainless steel (with the exception of the PTFE diaphragm)

Options

• Special work materials such as Hastelloy, zirconium, titanium, alloy 20, tantalum and plastics
• Diaphragm rupture display
• Pump head that can be heated or cooled
• Other designs of valve e.g. double valve etc.
• Special connections as desired
• Design according to API 675
• Special paint finishes are possible for example for offshore applications
• Electrical stroke adjustment
• High pressure design up to 700 bar
• Other options on request
