Hydraulic shock ( water hammer; fluid hammer) is a pressure surge or wave caused when a fluid, usually a liquid but sometimes also a gas, in motion is forced to stop or change direction suddenly; a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a…

Cavitation is a phenomenon in which rapid changes of pressure in a liquid lead to the formation of small vapor-filled cavities, in places where the pressure is relatively low. When subjected to higher pressure, these cavities, called “bubbles” or “voids”, collapse and can generate an intense shock wave Cavitation is a significant cause of wear in…

In , a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them. Although the term “fluid” includes both…

Amboretto Pump Transfer Skids (PTS)are designed for safely and efficiently transferring wastewater from process tanks or below grade sumps to Amboretto treatment systems. These pump transfer skids are easily integrated into our standard line of batch and continuous pH adjustment or heavy metal/fluoride precipitation systems. Specifications Simplex (one pump), duplex (two pumps), or triplex (three pumps)…

Chemical Dispense Systems (CDS) are designed for precise chemical injection. These systems use high quality corrosion-resistant metering pumps to inject chemicals into a process tank or piping manifold. These systems can be provided with a double-contained chemical supply tank or as a metering pump skid only. Custom configurations are available, call or e-mail Sales. Specifications…

Dosing system for adding dye. Skid was developed for applying dye in diesel fuel. In this model we have 3 applying points which are controlled automatically through the injection point through actuated valves with a closed loop system. The flow is determined by the diesel flow. This model can be used for other applications where…

Pneumatic plastic or metallic diaphragm pumps are positive displacement devices, linked to chemical-corrosive products, petroleum products, effluents, galvanic baths, ETA / ETE sludge and others. They have an excellent yield without pumping of viscous-corrosive products and with solid particulates. They can be placed as transfer pumps or discharge pumps. Pneumatic plastic or metal diaphragm pumps…

Gear pumps are also widely used in chemical installations to pump high viscosity fluids. There are two main variations: external gear pumps which use two external , and internal gear pumps which use an external and an internal spur gears (internal spur gear teeth face inwards, see below). Gear pumps are positove displacement (or fixed displacement), meaning they pump a constant…

Warman centrifugal pump in a coal preparation plant application Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.[1] Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or…
