Lift stations - Pumping stations

Municipal sewage pumping systems.

Low service time – non-return valves take less than 15 minutes to service. Quick service – easy access to the interior and possible revision of the pipeline without dismantling the valve. 


Compact construction of the pump canopy. A significant space saving is achieved through removing one flange one connection (valve and elbow), for a complete check sysyem.

  • 50 mm - 300 mm (1/2" to 12") flanged sizes available
  • 50 mm - 100 mm (1/2" to 4") Threaded sizes available
  1. Space saving – enables space saving in a pumping station allowing for installation of a much smaller tank.
  2. Quick replacement time – quickly replace valve balls without damaging the equipment.
  3. Full opening at the velocity of 0.7 m/s – the elbow ball check valves are fully opened at the velocity of 0.7 m/s, enabling efficient operation of the piping system.
  4. Significant reduction of vibration – Elbow mount check valves  reduce vibrations for more quietly system.



Elbow Ball Check valves may also be used in slurry lines for mine process control.


Pump check valves elbow mount design for lift stations and pumping stations back flow prevention.

Through the cover open in service position, the ball stops may be serviced without removing the valve .

Elbow ball check valves with rubberized coated ball check, also operates as a water check valve for use in hydrophore sets and wet wells.

Elbow mount ball check valves and combination of knife gate shut-off valves are used for self-actuating protection against reversible backflow. Threaded or flange connection models.

Reduce Pump Station size requirements using low profile elbow ball check valves.


COMBI Elbow and knife gate valves provide a manual cutting off of media by closing the knife gate valve. The knife gate valve is an integral part of the elbow check valve unit.


COMBI Elbow ball valves and gate valves (with threaded connection) and flange connections are used to automatically prevent return flow of medium from the pipe when the pump stops working.

COMBI type valves allows manually stopping the flow any time by closing the knife gate. They are used in sewage systems up to 40ºC and pH 4-8.



Combi Sizes Available:

Threaded Inlet / Flanged outlet - 2 inch
Flanged 125# (2 inch - 4 inch )



Check Valves Elbow mount design highlights

  1. Enables a more compact pump station.
  2. Low service time – Elbow mount ball check valves take less than 15 minutes to service.
  3. Quick replacement time – staff maintenance personal can quickly replace the valve balls in a simple procedure.
  4. Full opening at the velocity of 2.3 fps 
  5. Easy access to valves interior and the ball enables, placing the cover in the in servicing position.
  6. Reduce vibrations, very quiet operational noise.


Elbow Ball Check valves may also be used in slurry lines for mine process control.

Pneumatic Pressure Lift Stations: for small or large systems 3 inch to 6 inch pipelines.


Lift stations complete and fully automated installations, which do not require any constant operation by technicians.

They are intended to pump municipal waste in pressure sewage systems, in a wide range of capacities and delivery heads solely with the use of compressed air: a system without any pumps.

Pressure lines to gravity lines. Up to 340 ft. head lifts.


Technical data:

  • Patents no.: US 8,641,386 B2, US 8,347,912 B2.
  • Comply with harmonized norm EN 12050-1,2,4.
  • Comply with the requirements of the Directive: 89/106/EWG.
  • Lifting height up to 10 bars.
  • Pipe sizes from 3 to 6 inch

  • Sewage pumping over very large distances and/or heights (pumping pressure to 10 bars). FTH20 334 ft.
  • Municipal or industrial sewage.
  • Main, zonal or local lift station.
  • Pumping sewage in sections threaten by putrescibility in the discharge pipe (periodic aeration and/or emptying of the pipeline from the wastewater function).
  1. Refresh pumped sewage and prevent putrefying during transport.
  2. Allow periodic entire emptying of pressing pipeline using compressed air.
  3. Allow the possibility to adjust the efficiency of the lift station to the current requirements without replacing any equipment.
  4. Enable safe and hygienic operation by placing technological part in the dry chamber.
  5. Do not cause any silting or formation of sludge and surface scum as a result of sedimentation and floatation in the retention chamber.
