KNF LABOPORT SH 840 G IP30 Diaphragm Pumping System

The N 840.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automatic conde (more)nsate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products. The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications. When the humid gases are sucked in, it can happen that condensation forms in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection.

KNF UN820.3FT.40P IP44-T Diaphragm Pump Ultimate Vacuum 10.7 mbar (abs.) Maximum Flow Rate 20L/min  (more)(1.2 m3/h) Protection Class IP44 Features - Clean, 100% oil-free operation - Corrosion-resistant PTFE/FFPM flowpath - Ideal for extremely aggressive/corrosive gases and vapors - Compact, quiet and reliable - Self-drying system removes condensate without affecting the vacuum level - Maintenance-free The chemically-resistant series N820.3FT.40P diaphragm pump is a two-stge unit with an integrated PowerDry self-drying system. There is a wide range of applications for this pump in laboratories, especially whenever clean vacuum is required and moist gases must be pumped down. Examples include vacuum-drying of vacuum oven chambers (for drying or heat-treating substances and components) or steam sterilizers for sterilizing instruments, vessels, filters and textiles. Due to its high resistance to aggressive media, this pump can be used universally. The heart of these very compact pumps are KNF structured diaphragms (PTFE-coated). These patented diaphragms were stress-optimized using the Finite Elements method. As a result, we were able to make the pumps smaller while increasing the service life of the diaphragm. This pump is 115V.

Edwards XDS35i Dry Scroll Pump Ultimate Vacuum 1 x 10-2 mbar Inlet Connection NW40 Displacement 43 m (more)3h-1 / 25 ft3min-1 Features - Scroll pumps provide oil-free pumping, making them an excellent alternative to rotary vane pumps for clean applications - The XDS pumps feature an innovative bearing shield that isolates the vacuum environment from lubricants, ensuring a totally dry operation and protecting bearings from process gases - Adjustable gas ballast enhances vapor handling, allowing the pumps to be used in applications previously unsuitable for scroll pumps - Achieves a peak pumping speed of 35 m³/h (50 or 60 Hz) for rapid and effective operation - Capable of handling a maximum inlet pressure for water vapor of 35 mbar (23 Torr) - Operates at a nominal rotation speed of 1750 rpm for consistent performance - Exceptional leak tightness of <1 x 10⁻⁶ mbar ls⁻¹ for reliable and efficient operation Edwards XDS35i Dry Scroll Pump Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps.

Edwards E1M18 Vacuum Pump Ultimate Vacuum < 3x10-2mbar Inlet Connection NW25 Displacement 25.0 m3 (more)h-1 / 14.7 ft3min-1 Features - High ultimate vacuum and rapid pumping speed ensure efficient operation across a wide range of laboratory and industrial applications - Quiet operation provides a comfortable working environment, reducing noise in sensitive areas - Features a pressurized oil system that lubricates pump shaft bearings and rotor sealing faces for reliable performance - Maintenance is simplified with an oil sight-glass for easy monitoring of oil levels and conditions at a glance - Facilitates easy oil changes with an oil drain plug that allows either gravity or pressure oil drainage for convenience - Compact, freestanding design allows flexible use without the need for additional support structures - Ideal for use with analytical instruments, leak detectors, helium research, and for backing turbomolecular pumps, showcasing its versatility Edwards E1M18 Vacuum Pump The EM range of oil sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single phase or three phase (four pole) air cooled motor. Each EM pump is supplied with 2 x 1 litre of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately. This is a single stage oil sealed rotary vane pump which has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior after the pump stops. The pumping chambers are air-tight, so this arrangement also prevents suckback unless the gas ballast valve is open.You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.Click Here to View Product Video INCLUDED: The Edwards E1M18 Vacuum Pump includes: - 2 Liters of Ultragrade 19 Oil - O ring and centering ring - Two Allen keys and spares seal for oil drain and filter plugs - Operator's Manual - 1 Year Manufacturer's Warranty
