The Integra Bladder Pump

Integra Bladder Pumps are manufactured from 316 stainless steel and have Teflon check balls. The bladder most frequently used is Teflon, however polyethylene bladders are also available. 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 bladder pumps are more suitable. It has Teflon check balls, a porous polyethylene screen and may have either a Teflon or a polyethylene bladder. 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 lengths of 2 ft and 4 ft (0.6 m and 1.2 m). 1" dia. (25 mm) bladder pumps are also available for narrower applications and for use in the Waterloo Multilevel System. (See Model 401 Data Sheet.)

 

 

 

 

Portable Integra Bladder Pumps

For less frequent sampling, and to allow access to multiple monitoring wells, even in remote locations, portable Integra bladder pumping systems are available.

 

They may be supplied on a free- standing reel, or mounted on a cart with the tubing and pump controller. The rugged cart mounted system uses large pneumatic tires for easy transport over rough terrain. Bladder Pump Stainless Steel 1” (25 mm) on Free-standing Reel

 

Converts Easily to Pneumatic DVP (Double Valve Pump)

The 1.66" dia. (42 mm) by 2 ft (0.6 m) Stainless Steel Integra Bladder Pumps (42 x 610 mm) utilize most of the same parts as the pneumatic drive Solinst 1.66" Double Valve Pump (DVP). The DVP can operate from greater depths and provide higher flow rates. Conversion from an Integra Bladder Pump to a Double Valve Pump and back again is quick and easy (approx. 2 min.) and requires no tools.

Integra Bladder Pumps available in Stainless Steel 1” and 1.66” (25 mm and 42 mm) or PVC 1.66” (42 mm)

 

Dedicated Systems

For long term monitoring it is always best to dedicate Integra Bladder Pumps. This avoids cross-contamination and saves time without the need to decontaminate between sampling events. There is the assurance of no air/water contact during sampling, and the confidence that no cross-contamination will occur from the use of portable equipment.

Integra well caps are designed for ease of use. The vented PVC caps have a quick-connect attachment for the controller unit/air supply. Fittings are provided for both 1/4" OD (6 mm) and 3/8" OD (9 mm) tubing. Each cap comes with a 3 ft (0.9 m) length of 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. An eyebolt is provided for a pump support cable or for suspension of a Solinst Levelogger, (see Model 3001 Data Sheet) or other device.

 

Dedicated Well Caps

The caps slip easily onto 2" dia. (50 mm) wells. Adaptors to fit 4" dia. (100 mm) or other well sizes are also available. The cap seals in place with an o-ring, and comes with a wire connected protective cover. Low profile wellheads are also available for flush mount casing applications.
