KNF LIQUIPORT IP65 NF 1.100 FT.18RC Diaphragm Liquid Transfer Pump

The N 820.3 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, condensation may form 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.

VACUUBRAND PC 3004 VARIO Select Chemistry Pumping Unit Ultimate Vacuum 1.5 mbar (1.1 Torr) Maximum  (more)Pumping Speed 2.7 CFM at 60Hz Number of Heads/Stages 4/3 Features - VACUU·SELECT vacuum controller with graphical user interface and predefined applications simplifies work in the laboratory - Automatic boiling point detection and adjustment of the vacuum for short process times - Powerful vacuum pump meets high vacuum requirements for most high boiling solvents - Extraordinary diaphragm life, therefore minimum operational and servicing costs - Excellent environmental compatibility through low energy consumption and efficient solvent recovery The PC 3004 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. With its high pumping speed and deep ultimate vacuum, this pump is suitable for demanding applications with even high boiling point solvents. The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU·SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU·SELECT controller continuously detects the boiling point and automatically adjusts the vacuum process as necessary. And the VARIO control algorithm maintains the desired vacuum level without running the motor faster than necessary. This prevents bumping and foaming, makes the pump whisper quiet, and extends maintenance intervals. The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection. Typical applications are all evaporation processes. They can be run fully automatically and with shorter process times and extra sensitivity even for challenging mixtures at the same time. The VARIO® control ensures high process reliability through prevention of boiling retardation or foaming. It detects boiling pressures automatically and self-adapts to changing process parameters at any time. This all without any need of parameter input or the use of a solvent library. Also in many other applications and in laboratory vacuum networks the VARIO® control brings significant advantages as it provides always the appropriate pumping speed. The VACUU·BUS® interface facilitates an user-friendly configuration of even complex vacuum installations.INCLUDED: The VACUUBRAND PC 3004 VARIO Select Chemistry Pumping Unit includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
