Model 407 Integra Bladder Pump

Integras are manufactured from 316 stainless steel and have Teflon* check balls and a Teflon bladder. This is the ideal sampling pump for most types of municipal, industrial and general environmental applications, especially where VOC analysis of the sample is important.

For metals analysis and situations with highly corrosive liquids, the PVC Integra is more suitable. It has a Teflon bladder and check balls and a porous polyethylene screen. The low cost of the PVC pump also makes this a perfect choice for situations where there is a limited budget, but dedicated bladder pumps would be preferred.

The pump body of the standard Integra is a convenient 1.66" dia.(42 mm) and comes in standard lengths of 2 ft. and 4 ft. (610 mm and 1220 mm).

A 1ӯ (25mm) bladder pump is also available for narrower and/or deeper applications and for use in the Waterloo Multilevel System (see data sheet #401).

Dedicated Systems

With dedicated Integra Bladder Pumps there is the assurance that there is no air/water contact during sampling, and the confidence that no cross-contamination will occur from the use of portable equipment.

For long term monitoring it is always best to dedicate Integra Pumps. This avoids cross-contamination and reduces sampling time, and thus the ongoing costs of field time are also reduced.

Integra well caps are designed for ease of use. The vented PVC caps have a quick-connect attachment for the controller unit/air supply and a push-fit tubing connector for the sample line. Each cap comes with a 3 ft. (0.9m) discharge line which is easily replaced, as required.

For water level monitoring there is an access hole to fit a Solinst Model 101 Water Level Meter, or the size of the access hole can be specified. An eyebolt is provided for a pump support cable or for suspension of a Solinst Levelogger (see Data Sheet #3001) or other device.

The caps slip easily onto 2ӯ wells. Adaptors to fit 4ӯ or other well sizes are also available. The cap seals in place with an o-ring, and comes with a wire connected protective cover.

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, which ensures a representative sample at100 ml/min or less when sampling for VOCs. The standard #466 gives 160 psi and the 466HP offers 250 psi.

The Manual Controller is fully pneumatic with no batteries. It is ideal for those who wish to avoid batteries, or to have the most complete control over drive and vent cycles

The convenient boxes are rugged, dependable and suitable for all environments. Quick-connect fittings allow instant attachment to dedicated well caps or portable reel units and to the in-line dryer and compressor.
