Model 408 Double Valve Pump > Datasheet > Portable Systems << Previous
	For less frequent sampling, reel and/or cart mounted portable systems allow access to multiple monitoring wells, even in remote locations. The rugged cart mounted system uses large pneumatic tires for easy transport over rough terrain. Reel mounted portable units have a convenient carrying handle where tubing length permits. The Solinst Double Valve Pump utilizes most of the same parts as the Bladder Pump. The standard size is 1.66" dia. by 2 ft. (42 mm x 610 mm). Conversion from one to the other is efficient and easy (approx. 2 min.). It allows faster purging as a Double Valve Pump and lower flow, high quality sampling as a Bladder Pump when desired.

	The electronic controller uses 8 AA batteries that provide up to 30 hours of continuous use. It is fully automatic with preset sample modes to give a variety of useful drive and vent cycles. These can be further adjusted manually to optimize the flow. It allows faster purge rates and precise low flow to ensure a representative sample at100 ml/min or less when sampling for VOCs. The standard #466 gives up to160 psi and the 466HP offers 250 psi. ® Teflon and Viton are registered trademarks of Dupont Corporation
