HERON SMALL INTERFACE METERSmall Interface Meter
Smallest Interface Meter Available
The Sm.OIL Interface Meter meets the requirement for a small low cost high quality meter for use in shallow monitoring wells. Why pay for what you do not need?
The 60 ft/20m tape length of the Sm.OIL makes this the ideal unit for most monitoring wells.
The Sm.OIL uses the same technology as the popular HERON H.01L Interface Meter. The probes are field servicable and the electronics are fully encapsulated for environmental protection. The tape complies with US GGG-T-106E, a recognized standard assuring you of reliable, repeatable and accurate readings.
2” GAS DRIVE PUMPS
Constructed of Stainless Steel and Teflon , NSF rated PVC, or all Teflon materials, GEOPUMP 2" Gas Drive Pumps are ideal for ground water remediation pumping. With the inherent safety of fully pneumatic operation, these pumps may be used in ignition-prone situations without expensive, explosionproofing modification. With only two moving parts, the pumps are designed to survive sand, dry pumping and dirty air, cycle after cycle, and year after year. GEOPUMP 2" Gas Drive Pumps operate on a cyclic principle, with the duration of the discharge and refill cycles determined by a cycle controller. When a
compressed air charge is delivered to the pump, it causes the lower (intake) check ball to seat, simultaneously
forcing fluid through the discharge check valve and into the discharge tubing assembly. When the compressed air charge is removed, pressurized air vents from the pump, through the air tube, allowing the pump to refill.
STAINLESS STEEL / PVC GAS DRIVE PUMPS
Constructed from Type 316 Stainless Steel or PVC, GEOPUMP Gas Drive Pumps are ideal for ground water remediation pumping.
GEOPUMP Satellite Controllers are used in multiple well, ground water remediation projects to provide a low cost alternative to a primary pump controller at every well. Installed at each remote well head, the Satellite Controllers are connected to the primary cycle controller by 1/4" O.D. "logic" tubing. With pumping frequency determined by the primary controller's discharge and refill timers, pneumatic signals are sent through the "logic" tubing, which opens and closes Satellite Controllers, providing drive air to the remote, pneumatic recovery pumps. Each Satellite Controller can be independently adjusted to provide precise, variable, flow control over its
REMOTE LEVEL SHUT-OFF
The GEOPUMP Remote Level Shut-Off Device is a pneumatically operated, liquid level sensor. The device turns the air supply on and off automatically, responding to changes in water level in the well.
The shut-off device has been designed to quick connect onto the inlet air fitting of the Model 50015 Satellite Controller. When the level control valve is closed, no supply air is allowed into the Satellite Controller, which prevents the downwell pump from operating. As the liquid level in the well rises, the level control valve opens, allowing the supply air into the controller to drive the pump.
FULL TANK SHUT-OFF
The GEOPUMP Pneumatic Full Tank Shut-Off is a bubbler
activated liquid level sensor. Automatically responding to
changes in liquid level, the device turns the air supply to the cycle controller(s) off when the tank is full, thereby disabling the downwell pneumatic pump(s).
GEOPUMP Fully Pneumatic Cycle Controllers provide automatic control over downwell recovery pump fill and discharge rates. Housed in a non-metallic, watertight enclosure, the controller features easy to adjust, independent timers assuring optimal pump cycling frequency under any lift and submergence condition. Requiring no batteries or electrical power, the controller is available with or without automatic on/off level control for operating pneumatic pumps used for ground water remediation and/or leachate extraction.
Controller Manifold: The Controller Manifold, with quick exhaust valve, is used in single controller, multiple well systems to distribute the air signal uniformly to satellite controllers. The aluminum manifold plugs directly into the primary cycle controller.
Airline Assembly: Required for single controller,single pump applications, the Model 50090 Airline Assembly attaches directly to the primary cycle controller.
GEOPUMP Well Covers provide a means of terminating dedicated tubing to the well head, supporting the pump, and housing the air and liquid discharge fittings. The standard closure is a non-lockable flat cap, recommended where recovery wells are underground vaults or protective
REMEDIATION BLADDER PUMP
The GEOPUMP remediation bladder pump features a flexible bladder capable of suction. This allows the pump to operate efficiently in low submergence conditions, and can be positioned above the fluid column in conjunction with a product skimming attachment. Additionally, the bladder provides a barrier between the liquid and the drive air preventing volatile gas emissions. When used for total fluids pumping, the separation of drive air from the fluid eliminates metals precipitation. This pump can also be used for dense NAPL recovery without vacuum assist modules or a fluid column over the pump. The bladder pump can further be converted to a positive displacement gas drive pump by replacing the bladder with a dip tube
HIGH FLOW PVC BLADDER PUMPS
GEOPUMP high flow bladder pumps are designed for ground water remediation applications when air contact with the fluid is not desired due to the potential for metal precipitation. Many air driven pumps develop problems in these types of environments so the bladder membrane provides a barrier between the drive air and the fluid pumped. The membrane also prevents volatile gas emissions back to the environment during the exhaust cycle.
