Fasspumpe Bürkle

Manufacturer: Bürkle Model: Gas-tight stainless steel barrel pump discharge hose/stopcock P/N: 5611- (more)1090 Description: Gas-tight barrel pump is a pump with flexible discharge hose for filling off into large canisters and containers. It provides convenient transfer because the canister can stay on the floor. The connection cone is held onto the container. The gas-tight barrel pump enables odour-free transfer. During transfer with normal pumps, it is impossible to prevent vapours escaping into the atmosphere. The gas-shuttle method avoids this. Any vapours produced are returned from the container which is to be filled to the original container via the gas-shuttle pipe. The gas pipe and the liquid pipe are additionally provided with stopcocks. Gas-tight pumps are used for substances that have a strong smell such as ammonia. Not suitable for acetone!Please note: When withdrawing flammable liquids, the barrel and pump has to be grounded! Use Anti-static set!Features: - Parts in contact with media: Stainless steel AISI 304 (1.4301), PTFE, nickel-plated brass, PA that can conduct electricity- Incl. gas-tight barrel screw joints with 2" fine thread- For bottle openings from 16–49 mm- Immersion tube Ø 32 mm- The pump can be hermetically sealed with two ball valves Specifications: - Immersion depth: 57 cm- Total length: 69 cm- Pump capacity: 350 ml per stroke Items delivered: - Bürkle Gas-tight stainless steel barrel pump discharge hose/stopcock Condition: The pump is in excellent like new cosmetic condition. It is 100% functional tested and ready to be used.

The controller controls the electrical supply to the pump with the exception of standby speed control. It has no manual controls and can only be operated through the logic interface. To operate the nEXT-85 H pump you must connect it to your own control equipment and power supply or alternatively use the Edwards TIC Turbo Instrument Controller or TIC Turbo Controller. nEXT 85H pumps are supllied with an inlet-screen fitted into the centering O-ring for ISO version pumps and into envelope for CF version pumps. nEXT85 pumps with an NW 25 interstage-port are supplied with an inlet-strainer that fits into the interstage-port. The inlet-screen and inlet-strainer protect the pump against damage that would be caused by debris entering the pump. The nEXT 85 H pumps have a vent-port for venting the pump and vacuum system to atmospheric pressure. The pump is supplied with a manual vent-vavle fitted; this can be replaced with a TAV5 or TAV6 solenoid-operated vent-valve. The TAV valve can be directly controlled by the on-board controller. The nEXT pumps have a purge-port: an inert purge gas can be introduced protect the bearing and motor from corrosion. An optional vent-port adapter and purge restrictor can be fitted to the purge-port to control the flow rate of the purge gas and to filter the gas supply.
