Supplier: VACUUBRAND
Description: For use in explosive areas chemistry diaphragm pumps category 2 with ATEX conformity are available.

Supplier: VACUUBRAND
Description: The three-stage VARIO-SP® diaphragm pumps, with its variable speed drive system, attains significantly higher pumping speed and a better ultimate vacuum than the corresponding fixed speed pump. The brushless motor (maintenance-free) enables easy integration of the pump into other equipment, and operation independent of line voltage. The motor speed is either fixed or can be adjusted externally via electronic control signals for adaptation to process requirements.

Supplier: VACUUBRAND
Description: This VARIO® chemistry pumping unit optimizes vacuum conditions automatically by precisely and continuously adjusting the diaphragm pump´s motor speed. Thanks to the motor speed control the pump operates only when vacuum is needed, saving energy and reducing maintenance.

Supplier: Welch by Gardner Denver
Description: All standard WOB-L piston pumps are recommended for pumping vapors of aqueous solutions including buffers but not for acidic, basic or organic vapours or gases.

Catalog Number: (181-0339)
Supplier: VACUUBRAND
Description: This VARIO® chemistry pumping unit provides vacuum control by precise and continuous adaptation of the diaphragm pump's motor speed. The on-demand motor speed control extends diaphragm lifetime considerably.
UOM: 1 * 1 items


Supplier: VACUUBRAND
Description: These chemistry pumping units use chemical resistant solenoid valves to maintain process control. Once the first boiling point is detected by the controller, it maintains the pressure at this level. Pumping units can be configured to run one or two independent processes at the same time.

Supplier: VACUUBRAND
Description: The VACUU·SELECT controller simplifies your work and allows VARIO® select chemistry pumping systems to deliver unparalleled precision. The pumps run whisper quiet and respond to demand in real time by matching pumping speed to process conditions.

Supplier: VACUUBRAND
Description: <B>Chemistry diaphragm pumps: </B>Chemistry diaphragm pumps in equipment category 2 (e.g. for Zone 1) with ATEX compliance. These pumps are exceptionally well designed for the avoidance of ignition sources. They have good chemical resistance, are oil-free, have no friction surfaces and the suction chamber is hermetically sealed off from the drive unit compartment. Motor with flameproof enclosure and integrated, self contained overcurrent and overheating protection for direct 230 V/60 Hz single-phase connection. Diaphragm pump heads made of anti-static materials. Chemically resistant: Materials in contact with media; fluorinated plastics, stainless steel, FFKM. Gas ballast with separate inert gas connection. Pressure relief valves inside and at the outlet. Safety membrane technology with the option for inert gas flushing and membrane tear detection.

Supplier: Welch by Gardner Denver
Description: The MPC chemical duty diaphragm pumps use PTFE and other fluorinated plastics for the wetted parts to allow aggressive solvent and acid vapours to be pumped. If the pump should handle harsh chemical vapours, then the superior chemical resistant X2 version with higher grade seals and thicker coatings are the best choice. These are well known for quiet operation and running smoothness.
