Steps In The Process

After the initial decision that pumping equipment is required, purchasing of the equipment can be divided into the following general steps.

• Engineering of the pumping system

• Selection of the pump and driver type

• Pump specification and data sheet preparation

• Inquiry and quotation

• Evaluation of bids and negotiation

• Purchase of the selected pump and driver

In the process of specifying pumping equipment, the engineer must determine system requirements and system head curves, select pump type, write the pump specification, complete the pump data sheet, determine testing, inspection and vendor drawing and data submittal requirements and develop all the data necessary to define the required equipment from the supplier.

Having completed this phase of work, the engineer is then ready to take the steps necessary to purchase the equipment. These steps include issuing the pump inquiry to the bidders, technical and commercial evaluation of pump bids, selection of the supplier, and release of data necessary to issue the purchase order. The ultimate result of this process is the selection of a pump/driver combination that satisfies both the process and mechanical requirements.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
