1 Dependable conveyance with no overflow NEMO BT Immersible Pumps - special design for the petroleum industry tabposition1contentblockidentifiertab content In some cases the viscosity of the crude oil is so high, that it cannot be conveyed by a horizontally installed pump. Here the vertically designed NETZSCH progressing cavity pump offers an ideal solution. This design is also available as a Caisson pump and is characterized by extremely low NPSH values. Features of the NEMO BT Immersible Pump: tolerant to sand content in the medium low-pulsation conveyance high suction capability NEMO BT Immersible Pump offers you: acurate dosing precision low life cycle costs high pressure stability Advantages of the NEMO BT Immersible Pump operation possible even with high water content reliable operation with highly viscous oils suitable for media with high solid content tabposition2contentblockidentifiertab content Dependable conveyance with no overflow

2 1 Rotor In wear- and corrosion-resistant designs. 2 Stator Vulcanized into the tube with sealing on both sides in a variety of elastomers, plastics and metals. Stator inlet with funnel-shaped opening for improved feed of the product into the conveying chamber. The stator is oil-, acid- and alkali-resistant. 3 Drive Chain Coupling rod and two gimbal joints for the transmission of power from the drive to the rotor. 4 Shaft Seals Standard with single-acting, bi-directional, wear-resistant mechanical seal. Upon request, with single- or double-acting mechanical seals of varied designs and from various manufacturers, cartridge and special seals as well as packed glands. 5 Suction and Discharge Housing Flange and threaded connections in accordance with DIN and international standards. Materials in cast iron, steel, chrome-nickel-steel rubberized; also special materials upon request. 6 Block Construction The drive is flanged directly to the lantern of the pump, resulting in compact dimensions, low total weight, constant axial heights irrespective of the construction type and size of the drive, and ease of maintenance and serviceability as well as high efficiency. The NETZSCH NEMO BT Immersible Pump is available in chrome-nickel-steels duplex and super-duplex steels Hastelloy titanium special materials conveys capacities from a few ml/h to 120 m³/h pressures of up to 24 bar in standard form and offers a great variety of shaft seals such as: packed glands shaft sealing rings single-acting, bi-directional mechanical seals with and without quench double-acting mechanical seals (tandem and back-to-back) thermosiphon systems Certification / Credentials DIN ISO 9001 Certification in accordance with 19 WHG ATEX Directive GOST R and GOST K Material certifications Test reports Welding certificates Non-destructive material testing Sound level measurement Quality plans Progress reports Other certification and credentials upon request

3 tabposition3contentblockidentifiertab content NEMO Immersible Pumps special design for the petroleum industry Dependable conveyance with no overflow In the oil field, surface water mixed with crude oil accumulates in pits. These pits must be emptied. There can be considerable variation in the viscosity of this oil/water mixture, depending upon its temperature and the ratio of its components. NETZSCH Immersible Pumps convey this mixture reliably and securely to processing plants from depths of up to 15m. Wide Spectrum of Applications The NEMO Immersible Pump is used primarily for substances with the following properties low to high viscosity (1 mpas to 100,000 mpas) thixotropic and dilatant shear-sensitive abrasive non-smearing or smearing aggressive (ph 0 to 14) adhesive toxic such as crude oil crude oil polluted with water and sand oil/water emulsions water in oil deposits oil sludge Additional Features of the NEMO BT Immersible Pump: suction pipe extension can be mounted to lengthen immersed tube lowest possible NPSH bi-directional low noise, low vibration temperatures from -40 C to 160 C tabposition4contentblockidentifiertab content Accessories to supplement your system offer optimal security The following accessories are available for NETZSCH NEMO Immersible Pumps: A great assortment of shaft sealing systems planned in accordance with API 682 and seal sizes in accordance with API 610 Systems for monitoring the conveying pressure Dry running protection units Safety valves Electrical control systems A great variety of drive systems Tank lid and support guides
