We offer a wide variety of pumps, from small, lightweight pool pumps to large commercial air-operated diaphragm pumps with large volumes. Pumps are key components of many mechanical processes and machines, both those that operate automatically and by human control and initiation.

The plunger pump is an ancient, simple, and the least expensive of all pumps. It forms the basis for all other pumps. The simplest form of this device is a rod of wood or metal that is lifted into an upright position by means of a lever and then released to fall under gravity. When most people think of a pump, they are thinking of a plunger pump.

A number of factors affect the selection of a pump, such as the type and amount of liquid to be handled, the temperature, head and pressure available, the method of power supply, the price and performance limitations among other things. The type or sizes of pumps best suited for a specific situation can depend on the experience of those involved.There are three primary types of pumps: centrifugal, reciprocating, and positive displacement. Learn more about the different types of pumps in the table below.

The mechanical pump was invented in ancient times and remains in wide use today. Charles Parsons (1854–1931) patented the first successful rotary steam turbine, known as an impulse turbine. Knowledge about rocketry and jet propulsion has led to a wide variety of special-purpose pumps.

The pump is the heart of your septic system. It moves the septic tank effluent to the soil absorption field. Things that can damage a pump and affect its ability to move effluent include roots from trees and shrubs growing into and around the discharge pipe, frozen pipes, tree roots clogging the absorption field, effluent in the discharge pipe freezing in winter weather, back siphonage caused by unusually heavy flooding after pumping has stopped .This new high quality aluminum hand pump is constructed of metal, instead of plastic.

pumps are used to move liquids, slurries and gases from one location to another. There are various types of pumps depending on the application. Pumps fall under major groups according to the method they use to move the fluid, these groups include friction, transmission, and velocity pumps. A pump is a mechanical device that moves fluids or slurries. It consists of a pumping chamber with at least one inlet and one outlet, pistons to do work and a power source to supply energy for movement. This pump is a direct-acting rotary positive displacement type of pump. It can be used to raise the level of a liquid. operation requires an input of mechanical energy and consists of cycles with the following two phases:

Iran is the first country in the world that officially adheres to the Shi"a branch of Islam. Conquered several times by various empires, Iran has also had a long and tumultuous history, with periods of Persian Empires ruling over large areas of Eastern Europe, Africa and South Asia. At its zenith, Persia had built an Empire whose borders stretched from the Indus Valley in the east all the way to Turkey and eastern parts of Southern Europe such as Greece. Ancient Iran was also home to one of the oldest urban centers in human history – Susa, located in modern-day southwestern Iran.

Muslim conquest reached the North African coast during the life of Mohammed, but it was not until 647 that the Arab armies invaded Spain. By 718 a large area from south of modern-day Madrid to Lisbon had been conquered.

چیلر چیست؟

هدف چیلرها، چه صنعتی و چه تهویه مطبوع، انتقال گرما از یک مکان و انتقال آن به مکان دیگری برای خنک شدن است. چیلرها از آب یا نوع دیگری مایع،برای خنک کردن قطعه تجهیزاتی که می‌خواهند استفاده می‌کنند. مکانیسم پمپاژ در چیلرها محلول آب یا خنک‌کننده را پردازش کرده و به سیستم پمپاژ منتقل می‌کند تا منطقه مورد نظر خنک شود. پرکاربردترین نوع چیلر، چیلر هوا خنک تراکمی است.

چیلرها برای خنک کردن انواع محصولات به کار می‌روند و کاربرد آنها فقط عمل کردن به عنوان واحدهای تهویه مطبوع نیست. آنها برای خنک کردن محصولات، ماشین آلات، چیلرهای آب، قالب‌گیری تزریقی، صنایع غذایی و نوشیدنی و بسیاری دیگر استفاده می‌شوند.

چیلر میدیا دارای خط تولید کامل است، با طیف وسیعی از کاربردها برای برآورده کردن نیازهای متغیر مشتری تولید شده است. همچنین از فناوری تبادل حرارت طراحی نسل جدید تراکم دو مرحله‌ای برای افزایش راندمان در چیلر میدیا استفاده شده است. از طریق فناوری منحصربفرد تبادل حرارتی ثبت شده، حجم شارژ مبرد را می‌توان تا 40 درصد کاهش داد.

چیلرها برای خنک کردن ساختمان‌ها یا فرآیندها، آب سرد یا مخلوط مایع آب/گلیکول می‌سازند. چیلرها که اغلب همراه با کویل در هواگیرها استفاده می‌شوند، سیال گرم را از کویل هواگیر یا بار فرآیند دریافت می‌کنند، سپس بعد از آن دمای سیال را کاهش می‌دهند، سپس یک پمپ سیال را به کویل یا فرآیند هواگیر باز می‌گرداند. چیلرها در دو نوع اصلی وجود دارند: هوا خنک و آب خنک. یک چیلر هوا خنک، گرمای جذب شده از ساختمان یا فرآیند را مستقیما به هوای بیرون با استفاده از کویل‌های مبرد به هوا و فن‌هایی که هوای بیرون را مستقیما روی آن کویل‌ها می‌دمد، دفع می‌کند. یک چیلر آب خنک، گرمای جذب شده را به یک حلقه سیال اضافی دفع می‌کند که سپس می‌تواند گرما را از طریق یک دستگاه ثانویه مانند برج خنک کننده (متداول تر) یا خنک کننده خشک (کمتر رایج) دفع کند.
