Solinst Bladder Pumps
Solinst Bladder Pumps available
in Stainless Steel 1" and 1.66"
(25 mm and 42 mm) and
PVC 1.66" (42 mm)
Solinst Bladder Pumps are manufactured from 316 stainless steel and have PTFE or 316 stainless steel check balls. The bladder is made from durable Santoprene with a Delrin® and acetal copolymer cartridge. The stainless steel Bladder Pump is ideal for most municipal, industrial and general environmental applications, especially where VOC analysis of the groundwater sample is important.
The new PVC Bladder Pump is more suitable for metals analysis and situations with highly corrosive liquids. It has PTFE check balls, a porous polyethylene screen, and a Santoprene bladder with a Delrin and acetal copolymer cartridge. The lower cost PVC Bladder Pump is a perfect choice for situations with a limited budget, but dedicated Bladder Pumps are preferred.
The standard pump body of the Solinst Bladder Pump 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). Stainless Steel Bladder Pumps are also available in a 1" dia. (25 mm) for narrower applications and use in the Waterloo Multilevel System. (See Model 401 Waterloo Mulilevel System Data Sheet.)
Portable Bladder Pumps
Portable Bladder Pump systems are available for less frequent sampling and to allow access to multiple monitoring wells, even in remote locations.
Portable Bladder Pumps are supplied on a free-standing reel. The rugged systems are very convenient and easy to transport. The barb and compression tubing fittings on the reels and controller allow quick set-up in the field. Use a Solinst Model 103 Tag Line to lower and support the pump in the well (See Model 103 Tag Line Data Sheet).

Well Caps for Dedicated Bladder Pumps
Dedicated Well Caps
Dedicated well caps slip easily onto 2" dia. (50 mm) wells. Adaptors to fit 4" dia. (100 mm) wells are also available. They have quickconnect fittings for the drive and sample tubing.
Groundwater Sampling with a Dedicated Bladder Pump using Portable, Rugged, Easy-to-use, Compressor and Controller
Dedicated Systems
For long-term groundwater monitoring, it is always best to dedicate Bladder Pumps. Dedication avoids cross-contamination and saves time without decontaminating between sampling events. There is also the assurance of no air/water contact during sampling and the confidence that no cross-contamination will occur from using portable equipment.
Solinst well caps are designed for ease of use. The vented 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 can be easily replaced as needed.
There is an access hole for water level monitoring to fit a Solinst Model 101 Water Level Meter. or Levelogger. An eyebolt is provided for a pump support cable, a Solinst Levelogger suspension line (see Model 3001 Levelogger Data Sheet), or other device.
Use the New Solinst Bladder Pumps without the Bladder
An advantage of the Bladder Pump is the ability to also use it without a bladder. This allows you to continue sampling if you are in the field with no bladder replacements. Simply operate it like a Double Valve Pump (DVP).
