Pumps
Vacuum Pumps create and control vacuum conditions for processes such as rotary evaporation, freeze drying, filtration, drying and degassing as found in chemistry, biology, and material sciences labs.
Peristaltic Pumps (also known as Hose or Squeeze Pumps) rely on rotation rollers or shoes to compress and relax tubing thus creating a wave-like motion that propels fluids. They are ideal for handling sensitive fluids as found in medical or pharmaceutical environments for drug delivery. Peristaltic pumps are also suited for any application requiring precise and contamination-free fluid transfer such as chromatography or bioreactors.
Syringe Pumps utilize a motor-driven plunger within a syringe barrel to provide precise and controlled flow rates. These pumps are ideal for laboratory research and drug infusion, as well as other applications where small volumes and precise flow rates are critical.
Drum Pumps handle liquids that are hazardous, viscous, or otherwise difficult to pour manually. Drum pumps typically consist of the pump unit attached to a long tube or hose that is inserted into the drum containing the liquid and are available in different configurations (such as rotary, piston, or electric) based on the type of liquid being transferred.
Hand Vacuum Pumps create a vacuum to allow air or gas to be removed from a sealed container. These manual devices are hand-operated and are commonly used for fluid transfer and handling, siphoning, water aspirators for filtration, bleeding fluid lines, or checking for leaks.
Water Sampling Pumps collect water samples from rivers, lakes, oceans, groundwater, wells, and other sources. They ensure that the collected sample is representative of the water source and is contaminant free. Common mechanisms used to draw sample water include peristaltic pumps, submersible pumps, or bladder pumps. Designed to meet EPA, NPDES guidelines.
Pump Parts and Accessories ensure pumps maintain safe and efficient operations. Parts may include plunger assemblies, seals, gaskets, heads, valves, controllers, and vacuum traps.
