Vertical Sump Pump Provided for Oil Storage Application

When a major energy pipeline company looked to streamline their pumping system for their oil storage tanks, they called on NETZSCH to design and build customized vertical cavity sump pumps for lower maintenance and operational efficiencies.

 

Background

Along the customer’s pipeline are pumping stations needed to power the liquid fuels through the pipeline. At each pump station, there is a underground storage tank used as a collection point for excess oil from service work that is performed on main pipeline pumps. As the collection tanks fill to capacity, the customer needs to pump the liquid from the tank back into the pressurized pipeline.

 

Challenge

This process had consisted of a two-pump system – with a cantilever pump used to lift the excess oil out of the tank and a high-pressure piston plunger injection pump to move the oil back into the pipeline system.

 

Solution

NETZSCH progressive cavity pumps are tailor-made for this application, with dimensions to fit the customer’s existing underground tank. This pumps are also designed to operate in reverse, requiring the seal to be on the discharge side and the entire housing to be pressurized. The space-saving design of the entire pump disappears into the tank, providing for a very neat and clean installation. This also means that there is no additional effort needed to heat and isolate external equipment – a very important attribute in ambient operating temperatures down to -40°C. No concerns or issues from field operators. With the success of this installation, the customer has changed their current specification regarding these sump pumps to include or recommend the use of the NETZSCH pump for this application.

Products

Downstream – NEMO® Transfer Pumps

Great distances must often be covered in order to reach ports or refineries. Pump systems that can maintain a high conveying pressure at the lowest possible pulsation are required for such applications.

NEMO® C.Pro®

The NEMO® N-Ipos CY C.Pro® Dosing Pump is a fully synthetic pump for the precise dosing of a great variety of chemicals in environmental technology and the chemical industry. Its synthetic construction makes it perfectly suited for the gentle and low-pulsation conveyance and dosing of aggressive or non-aggressive chemicals.

Downstream – NEMO® Multiphase Pumps

Only very seldom does crude oil arrive at the surface in pure form. Usually it is mixed with water, sand and gas. Conventional pumps require that the gas first be separated from the crude oil. With NETZSCH NEMO® Multiphase Pumps, this is not an issue. NEMO® Multiphase Pumps can be used for crude oil with a gas content of up to 100%.

NEMO® SY Industrial Construction in Bearing Block Design with Free Shaft Extension

The NEMO® SY Progressing Cavity Pump is used for demanding applications in every branch of industry around the globe. In bearing block design with free shaft extension, this pump can be run with any type of drive, such as servo motors, diesel motors or hydraulic drives.

Downstream – NEMO® Water-Injection Pump

Crude oil deposits are often discovered in spongy rock. To extract it, fluids must be pumped into the earth under high pressures. NEMO® Water-Injection Pumps are particularly well-suited for this task, since their capacity can be changed in accordance with rotation speed.

NEMO® Pump BY

NEMO® BY Progressing Cavity Pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed.
