Variable Start-Stop Dispensing
Aalborg Instruments’ (Orangeburg, NY) TPV RP Adjustable RPM
with Dispensing Peristaltic Pumps can be timer relay set to start dis-
pensing liquids for a selected time period and to stop dispensing for
another selected time period. Features include:
A speed range from 0 to 300 RPM.
A flow range from 0 to 5,000 ml/min (1/2" ID tubing).
An adjustable pump handle.
Priming, dynamic braking, RPM setting, and flow direction
7 time intervals.
3 stainless steel rollers and stainless steel shafts.
A fixed occlusion wall.
A maintenance-free 24 VDC brushless motor.
Swagelok (Solon, OH) has expanded its medium- and high-pres-
sure product line with the addition of IPT series products. The series
includes precision valves, fittings, and fluid control devices suitable
for surface and subsea systems. The product line features:
Check valves that reverse flow where leak-tight shutoff is required.
Ball valves to accommodate up to 20,000 PSIG (1,378 bar).
Relief valves that have a max working pressure up to 20,000 PSIG
(1378 bar) and are available in 3/8" to 3/4" pipe ends.
Needle valves in 6 body styles for a range of applications with max
working pressures up to 60,000 PSI ( 4,136 bar).
Medium- and high-pressure tubing and nipples that are seamless,
austenitic, cold-drawn, tested, and inspected.
Coned and threaded fittings.
Metal Switch Glows Tough
Robust stainless steel switch with back lit ceramic actuator
resists scratches, abrasions and chemicals
- Momentary action
Diluting & Proportional Fluid Control
The STH and STQ duplex metering pumps from Fluid Metering
(Syosset, NY ) are ideal for precision mixing, diluting, and proportional metering for OEM medical, analytical, and industrial instrumentation. FMI’s OEM duplex metering pumps consist of 2 FMI valveless
pump heads direct coupled to a single variable stepper motor drive.
Independently adjustable pump heads.
Dispensing ratios from 1:1 up to 500:1.
A valveless pump design that eliminates multiple syringes, valves,
actuators, and drivers.
Maintenance-free cycles at ±1% precision (no recalibration).
A unidirectional continuous flow, utilizing 2 separate ports for
input and output.
