Scania Pumper from Station 2, West Melbourne at Etihad Stadium Melbourne Docklands, having been on Display for Good Friday.
A closer view to the north end of the little building of unknown purpose at Toddington station, as seen in the previous photo, plus what appears to be an ancient petrol pump mechanism?
This old treasure is loving cared for by Ralph, Lynn and Chris. The property is part of the James River Park System. It was built long ago to supply water for the fire hydrants in Richmond. It is a beautiful building.

Old gas pump.Original Sinclair H-C gas station Toccoa,GA. Price last time this was used 28 cents a gallon.
The restored steam engines at the Abbey Pumping Station in Leicester. Three of the engines are fully restored and operational - work continues on the fourth.
All four were built in Leicester by Gimson and Company and are Woolf Compound rotative beam engines. They are rated at 200 horsepower at 12-19 rotations per minute and could pump 263 litres of sewage per second.
In my previous upload of Sanders Omnicity captured at Swannington working a journey on service 42, I referred to the village pump. Here we see the memorial plaque attached to the wood encased pump. The inscription reads “In loving memory of HASTINGS PARKER - Placed here by his wife for the use of those whom he loved so well - 1888” The spout is below the plaque and the pump handle is at the back, there is another memorial to Mrs Parker on the left hand face.
Jet Pump volute chamber and impellers are designed to give the best possible hydraulic efficiency and good suction lift characteristic. Most modern and highly sophisticated machinery and technology are employed in jet pump. - www.atcomaart.com/pd/54677048555068566966/shallow-well-je...
Bicycle inner tube stretched over the end of a Vacuvin pump to create a cushioned seal between the hard plastic of the Vacuvin and the hard metal surface of a jar lid.
This allows the use of a Vacuvin wine saver pump on storage jars with home-made valves to vacuum dry-store food.

Black leather pumps (Chloé) because I didn't have a lot of time to think about my outfit. Palo Alto.
I think it was called the "pump house". It always scared me because sometimes the door would be open and all you could see in the pitch dark was a huge hole in the ground. There used to be a few steps leading to the entrance which we often ran up and down.
The former Great Western Railway pump house at St Catherine's Meadow, Gloucester. It was used to pump water from the River Severn for locomotive use at Gloucester station. This picture was taken in March 1991, since which time it has steadily become more and more derelict.

Reverse Osmosis is the reverse process of natural osmosis. Solutions with low salinity and low density have a natural tendency to migrate to solutions with high salinity and high density. Reverse osmosis membrane divides the water into two pass way, the Permeated water pass through the RO membrane to the clean water tank, and the rejected water going to the waste solution tank. The RO system will remove the majority of dissolved salts, contaminants, bacteria, and things that make water taste bad. By applying pressure the efficiency of purifying water is greater than the naturally Reverse Osmosis.
When water pressure is under 40 PSI, The RO system may generate less RO water while having more contaminant in the RO water. Most RO membranes need a water pressure of at least 60 PSI. A LEFOO RO AC pump will bump the water pressure to 75 PSI. LEFOO also offers custom RO pumps with over 80 PSI pressure.
REVERSE OSMOSIS PRE-PERMEATE TREATMENT
Pre-Permeate is critical for the lasting of an RO water system to prevent fouling, and too frequent cleanings, and premature failure of the span RO membrane. Here is common RO system issues about Pre-Permeate
Fouling happens when contaminants accumulate and clogging on the membrane surface. There are many contaminants in municipal feed water that are naked to the human eye and harmless for human consumption, but large enough to quickly foul (or clog) an Reverse Osmosis System. Fouling typically exists in the front end of a bare RO system without filters and results in a lower actual RO pressure and a lower permeate flow.
FOULING CAN BE CAUSED BY THE FOLLOWING:
1.Particulate or colloidal matter (dirt, silt, clay, etc.)
2.Organics (humic/fulvic acids, etc)
3.Microorganisms (bacteria, etc). B
4.Breakthrough of filter media upstream of the RO unit. GAC carbon beds and softener beds may develop an under-drain leak and if there is not adequate post-filtration in place the media can foul the RO system.
5.SCALING: An example of a common scale that tends to form on an RO membrane is calcium carbonate (CaCO3).
6.CHEMICAL ATTACK: Oxidizers such as chlorine will 'burn' holes in the membrane pores and can cause irreparable damage.
7.MECHANICAL DAMAGE
'Dry Start' may generate excessive back pressure that can cause permanent membrane damage, you might need a pressure switch to protect the RO system.
PRE-PERMEATE SOLUTIONS
Here are Pre-Permeatesolutions for RO systems
1.A Multi-Media Filter (MMF)is used to help prevent fouling of an RO system.
It is important to have a 5 micron cartridge filter placed directly after the MMF unit to prevent the MMF media from damaging downstream pumps and fouling the RO system.
2.Microfiltration (MF) is effective in removing colloidal and bacteria matter and has a pore size of only 0.1-10µm.
3.Antiscalants and scale inhibitors are chemicals that can be added to feed water before an RO unit to help reduce the scaling potential of the feed water.
4.A water softener can be used to help prevent scaling in an RO system by exchanging scale-forming ions with nonscale forming ions.
5.By adding sodium bisulfite (SBS or SMBS), which is a reducer, to the water stream before an RO at the proper dose you can remove residual chlorine.
6.Granular activated carbon is used for both removing organic constituents and residual disinfectants (such as chlorine and chloramines) from water.
Those Pre-Permeate Solutions need correct designs, maintenance programs, and experienced service support, your RO water system could serve many years of high purity water. Most RO membranes need at least 60 psi pressure to work well, if the water pressure is too low you need to retrofitted an AC RO pump.

Stretham Old Engine at dawn.
The steam-powered pumping engine just south of Stretham in Cambridgeshire, England. The engine was built in 1831 and at the time it was thrusting new technology, replacing four nearby windpumps to keep the surrounding fenland drained. Standing on the banks on the Old West River (part of the River Great Ouse), it used its scoop wheel to lift water from drainage channels in the lower fields for over 90 years. In 1925 it was superseded by a centrifugal pump powered by a diesel engine, but remained as a backup for heavy floods right up until 1941.
Today the engine and pumping house have been restored and are maintained as a museum that is open on the second Sunday of each month.

This area is full or dinosaur remains and home to the Royal Tyrrell museum, I think its a mark of geological time that the dinosaurs once roamed this area and the lone oil well pump on top of the hill is now recovering the remains of the dinosaur era.
Pump panel of Engine #1101 of the Warrenton Volunteer Fire Department. I wanted to bring out all of the details of the pump panel using a glancing shot up and across. Capturing the mid-day sun reflecting off a chrome panel "dots" the eye! I really like this shot in black & white.
