Static Pump HEAD, what is it?
The Static Pump Head is a term used to indicate the highest point which a pump must deliver a specific volume. Think of the highest point of a persons body. It is the head when standing upright. Static head is the head determined by the vertical height of the pipe system only. This is simply the actual height above the pump center body. Static head is not concerned with the developed back-pressure in the pipeline. There is another aspect that has influence on static pressure. Suction lift When one is drawing water from below the pump, the length of the pipe that extends below the pump to the surface of the water, is also a static measurement. This is known as suction lift and is normally added to the static head. A pump with a 3 meter suction lift and a 50 meter discharge static head will have a combined static head of 53 meters. Beware of Friction Losses The static pump head must not be assumed to be the total head of the pump when selecting a pump. It is important to recognize the other factors that will influence the total head the pump will need to develop. Static head is at best the basic measurement of the demand on the pump. Friction losses and equipment losses will add to this head substantially if the pipe system design is not carried out by a competent person.
Pedrollo submersible water pumps
Pedrollo Submersible Water Pumps Pedrollo submersible water pumps have many options from our water pumps catalogue please phone +27 31 777 1629 for service or email support@pedropumps.com Having moved our web presence from our well supported old site www.pedrollopumps.com, we were very apprehensive that folk looking for Pedrollo pumps would not find us. However the site seems to be ranking even though we have not been able to completely load all our products yet. Pedrollo submersible pump options are as follows:- Centrifugal pumps Submersible well pumps are centrifugal pumps, some of multistage design, others are single impeller units. Our Pedrollo 4 SR range is a borehole pump (deep well) and is fully supported from our warehouse in Durban and Cape Town, South Africa. Our Johannesburg distribution is being established this year 2016. When it comes to requiring an industrial pump for effluent, sewage or simple water pump duty, Pedrollo has a unit for your application. Most sewage pumps fall under our submersible pumps series and we have just completed a major upgrade to many of our models. These sewage pumps are suitable for handling fluids with entrained solids and fibrous materials. Equipped with silicone carbide seals the units are designed for efficiency and longevity. In terms of the electric water pump market sump pumps make up a relatively large volume of pump types used. Sump pumps typically mount inside a sump and are found to be transferring various industrial waste fluids, reliably and consistently over long periods of time without needing major maintenance or service. A variation on the standard type of sump pump is the TOP series and the RX series which channel the fluid being pumped over the motor. This design allows the pump to draw fluid far lower in the sump, cooling the motor and avaiding frequesnt overheating issues that can present problems in other types of submersible sump pumps.
