mill disharge pump valves

Modulate Centrifugal Pump Capacity - Engineering ToolBoxThrottling can be carried out by opening and closing a discharge valve. Throttling is energy inefficient since the energy to the pump is not reduced. Energy is wasted by increasing the dynamic loss. Bypassing Flow. The discharge capacity can be regulated by leading a part of the discharge flow back to the suction side of the pump.MDX Mill Duty Xtra Heavy Pump | KSBKSB delivers non-stop solutions for boosting productivity and profits.

A pump's outlet (discharge) piping flow characteristics normally will not affect the performance and reliability of a pump, with a few exceptions. In some cases, sudden valve closures can cause excessively high pressure spikes (surge or water hammer) to be reflected back to the pump, possibly causing damage to the pump ...Typical P&ID arrangement for pumps - EnggCyclopediaA check valve should be normally provided on the pump discharge to avoid reverse flow when the pump is not in operation. Downstream to the check valve on the pump discharge, minimum flow recirculation line for the pump needs to be provided. A flowmeter should be provided before the minimum flow line, as shown on the presented sample drawing.Metso MD Series horizontal mill discharge pumps - MetsoEngineered specifically to meet the needs of today's mill discharge operations, Metso MD Series horizontal mill discharge pumps will help you minimize problems, extend time between maintenance stops and lower your total cost of ownership.
