LLC-3 Sump Pump Level Controller
This is a traditional “float type” system designed for a 5 gallon pail or sump of equal depth. The pump is controlled by an internal float which actuates an air valve. As the liquid level in the sump rises, the pump automatically starts and operates until the liquid level drops below a predetermined level. The LLC-3 sump system cover comes complete with a diaphragm pump from the list below, float assembly (actuator and float ball with stem), filter-regulator gauge assembly, and suction pipe. All components are mounted on a 5 gallon lid and bucket.

Pulsation measurement without AD dampener.

For fluids with high solids content, Yamada^®AD dampeners incorporate a flow-through design which keeps solids in suspension, maintaining dampener effectiveness. Yamada^® AD dampeners do not restrict fluid flow, or increase fluid pressure, but compensate the voids and pressure fluctuations created by an air-powered double diaphragm (AODD) pump.

Yamada® Diaphragm Pump Pulsation Dampeners

FEATURES

• Flow through desing keeps solids in suspension
• Totally automatic air motor-self relieves if discharge head reduces
• Low air consumption
• Bolted construction
• PFTE coated air side optional

PRINCIPLES OF OPERATION

Compressed air is introduced to the top section of the pulsation dampener at the same operating pressure of the pump. When the air opereted double diaphragm pump produces a pulse, fluid will enter the in-line dampener. As fluid enters the dampener, the trapped air behind the dampener is compressed. The fluid remains in the dampener until the system pressure returns to normal or when the pump begins another cycle. The fluid is then pushed back into the system piping as the trapped gas expands. The dampener does not restrict fluid flow, nor increase its pressure, but fills the voids and pressure flunctuations created by an air operated double diaphragm pump.

APPLICATIONS

Metering / Injection / Dosing:  smoothing out discharge flow, increasing accuracy

Filter Press / Inline Filters:  Increase filter efficiency by providing smooth flow.

Spraying:  Smooth and consistent spray pattern is easilty accomplished.

Filing:  Eliminates inconsistent filling and splashing.

Transfer:  Eliminates harmful water hammer, which damages piping and valves.

INSTALLATION

Mount the pulsation dampener as close to the pump as possible. This will allow the pulsation dampener to see as much operation pressure as possible, which will increase pulsation dampener efficiency and effectiveness.

If the pulsation dampener is to be used in a low head application, you may need to add a control valve after the pulsation dampener to restrict flow and increase resistance.

Mount the pulsation dampener in a horizontal position. Vertical positioning is acceptable if you are pumping a clear fluid.

GENERAL PUMP INFORMATION

The post Yamada® Ultimate Diaphragm Pumps appeared first on Politek Vietnam Import Export Services Trading Company Limited.

Yamada’s AODD pumps are compliant with FDA regulations and are specifically designed for use in the food, pharmaceutical, and cosmetic industries. These pumps are comprised of a series of features including 316 stainless steel wetted components with a passivated satin finish, PTFE-coated air motors, and sanitary clamp fittings. Passivating refers to the process of modifying the surface layer or coating it with a thin inert layer to protect against contamination.

These pumps are also available with FDA compliant elastomers such as Hytrel^®, EPDM, and PTFE.

MATERIAL TYPE

The Split Manifold pump’s unique feature is its ability to have multiple inlet and outlet port configurations. This means that the pump can be used to pump or combine two fluids with similar specific gravity, such as antifreeze and water. This feature allows for more efficient and cost-effective pumping, as it eliminates the need for two separate pumps.

For example, a dual suction/single discharge Split Manifold pump could be used to mix two fluids, such as antifreeze and water. In this configuration, the pump would have two suction ports and one discharge port. The pump would draw in equal amounts of antifreeze and water from each suction port, and then combine them before discharging the mixed fluid out of the single discharge port.

Another example of a Split Manifold pump configuration would be a dual suction/dual discharge pump. This type of pump would be suitable for pumping two different colors of ink to separate locations. In this configuration, the pump would have two suction ports and two discharge ports. The pump would draw in one color of ink from each suction port and then discharge each color out of its respective discharge port, ensuring that the colors do not mix.

In summary, the Yamada Split Manifold pump is a versatile and efficient pump that can be configured to multiple inlet and outlet port combinations. This feature makes it ideal for pumping or combining two fluids with similar specific gravity or for pumping two different fluids to separate locations.

Yamada^® specializes in manufacturing high-pressure diaphragm pumps with a 2:1 ratio that are specifically designed to meet the demands of applications that require more than the standard 100 PSI pump operating pressure.

These pumps are capable of achieving a maximum discharge pressure of 180 PSI with only 100 PSI air inlet pressure supplied. Although the flow rate is approximately half that of equivalent size pumps, the double discharge output is made possible by applying air pressure to both diaphragm surfaces.

One of the key advantages of these pumps is that they do not require elaborate bypasses, relief valves, or complicated controls. Additionally, they offer excellent pressure retention capabilities.
