this month's topic Fluids HandlingHose Withstands Pressure And Temperature Extremes
Silbrade silicone hoses are reinforced with open-mesh polyester braiding so they can handle high-pressure applications. This construction allows the hoses to be used in tight, restricted spaces without impediments to flow. The hoses handle steady or fluctuating temperatures between –80°F and 350°F (–62°C and 176°C). Each hose is made from FDA-sanctioned ingredients and is listed by the National Sanitation Foundation for use with food equipment materials (NSF 51). It is odorless, tasteless, unaltered by the effects of weather, and generally exhibits inertness to UV light, radiation, and ozone.

Positive-Displacement Liquid Flow Calibrators are Very Precise
PDCL Series positive-displacement liquid flow calibrators cover flows ranging from 0.01 gal/min (0.04 L/min) to 400 gal/min (1,514 L/min) with an uncertainty of ±0.05% and a repeatability of 0.01% of reading. These volumetric devices displace an exact known volume of fluid, which passes through the flowmeter under test while compensating for fluid viscosity and temperature. They perform NIST-traceable calibrations of common flowmeters, including turbine, differential-pressure orifice plate, rotameter, variable area, coriolis, and any other type with a visual, pulse or analog output. Each PDCL calibrator has a precision-honed and polished cylinder assembly, with a piston mechanically connected by a displacement shaft. Piston travel is measured with a high-resolution linear encoder. One piston side is actuated pneumatically, while the other displaces a controlled amount of fluid through the meter that is being tested. Flow is regulated by three control valves — course, medium and fine — to obtain the required flowrate. The fluid is collected in a reservoir tank and returned to the cylinder, bypassing the tested meter. A temperature control system maintains fluid temperature to create the desired calibration conditions. The calibrator can be fully automated to establish flowrates and collect calibration data. Other automated features include automatic fluid air bleed; a servo-driven, telescoping flowmeter section; and a flowmeter-clamping fixture.

Durable Syringe Pump Is Easy to Read
KDS EZflow 2010 is a durable, basic syringe pump that enhances the speed and efficiency of operation. It can be used for infusions ranging from 0.1 to 300 mL/h, with an accuracy of 2.5%. Its easy-to-read light-emitting diode (LED) display — which is visible from many angles — shows the flowrate in mL/h or can be toggled to show the total volume delivered in mL. A variety of syringes from 20 mL to 100 mL can be used with the unit. A rapid delivery key eliminates dead volume and excess air in the tubing prior to delivery of the fluids. The pump has visual and audible alarms for four conditions: occlusion detection, low battery, near-end of dispense, and complete. The EZFlow 2010 is designed to work with 115 volts alternating current (VAC). Both units have a rechargeable battery and can operate on 12 VDC.

Caustic Soda Injection Pump Has No Valves
This caustic soda pump uses a single rotating and reciprocating ceramic piston to accomplish both the pumping and valving functions. This eliminates the need for the check valves typically found in diaphragm pumps; such valves are subject to caustic soda crystallization, which affects sealing and allows backflow.
