VTP Semi-submersible vertical turbine pump

The VTP series vertical turbine pump

 summary

The VTP series vertical turbine pump is a single suction and multi-stage vertical guide vane water pump, which adopts mixed flow and centrifugal impellers, and is matched with high-performance self-lubricating water guide bearings, with a long service life. It can be used with a corner gearbox and can be driven by a diesel engine. The underwater length can be customized according to user requirements. This series of vertical turbine long shaft pumps is an advanced and mature long shaft pump series product developed by absorbing advanced experience in the design and manufacturing of vertical long shaft pumps at home and abroad, and combining with domestic market demand. It has the characteristics of high efficiency, reliable operation, fast start, compact structure, and small footprint. It is suitable for conveying clean water, rainwater, seawater and other media in industries such as electricity, metallurgy, firefighting, mining, steel, and municipal engineering. It is widely used in flood control and drainage, dock water treatment, cooling services, seawater and raw water, industrial process pumps, public design circulating water, condenser circulating water pumps, flushing dust, firefighting, deep well water lifting, and municipal tap water.

Usage conditions

1. During the operation of the water pump, a certain submergence depth must be ensured, and the minimum submergence depth value can be found in the pump's safety installation dimension diagram.

2. Water should not contain any oily substances.

3. Water should not contain excessive corrosive minerals.

4. The sand content in water shall not exceed 0.01% by weight.

The pH value of water should be between 6.5 and 8.5, and special customization is required if it exceeds this range.

6. The well should be upright.

Driver type

The VTP series vertical turbine pump has four driving forms: 1) directly driven by a regular vertical motor; Ii) Directly driven by a vertical hollow shaft motor; Iii) Equipped with diesel engines or steam turbines for variable speed drive through a right angle gearbox; IV) Equipped with a horizontal motor and driven by a right angle gearbox for variable speed.

classification

The pump equipment mainly consists of three parts: pump body components, lifting pipe components, and pump seat components. The first two parts are located underground, and the pump seat part is located above the well.

VTP vertical turbine long shaft pumps are divided into the following four products based on impeller type and driving mode:

1. LC type single stage or multi-stage centrifugal pump or mixed flow pump (corresponding to API 610 VS1 pump) for high head, where the vertical multi-stage guide vane centrifugal pump can be extended to a vertical cylindrical bag pump (corresponding to API 610 VS6 pump).  

2. HLB (K) single stage mixed flow pump (oblique flow pump) for high flow rate and medium head.  

3. ZLB single stage axial flow pump (corresponding to API 610 VS3 pump) for high flow rate and low head.  

vertical turbine pump driven by a right angle gearbox for firefighting and offshore platforms or areas with insufficient power supply.

Materials Of Major Parts

The VTP series vertical turbine pump has a smaller ground area, making it safer and more reliable than submersible pumps; No need for irrigation and can be started at any time;

Has a unique sand removal structure that can adapt to water containing sand; By using a variety of different materials, it can adapt to various media.

VTP series vertical turbine pump material: stainless steel 304316316L, cast steel ZG235-450, cast iron QT400-18 or HT250, duplex steel 2205 or 2507.

Note: The material can be selected according to user requirements. The ones with ☆ are vulnerable parts, and the semi open impeller structure does not have sealing ring parts.

Other materials are  available at the request of clients.Cast iron is suitable only for closed type impeller.

Structural characteristics

◆Water outlet elbows larger than 10 inches are welded components. Suitable for high-temperature liquid pump transportation.

◆The external connecting pipe and guide vane body are both connected by flanges and positioned with a stop, which is convenient for assembly and disassembly during maintenance.

◆The external connecting pipe with stop positioning has low cost, convenient maintenance, and fewer malfunctions.

◆The transmission shafts are connected by key type couplings for easy maintenance.

◆When pumping media with particulate matter, a closed transmission shaft design with protective tubes can be used, and external flushing water can be used to flush the guide bearings, suitable for pumping corrosive and abrasive media.

◆There are various bearing materials available for selection, such as rubber, dragon, carbon fiber, ceramics, etc.

◆The replaceable shaft sleeve surface has been hardened to extend its lifespan.

◆The impeller and guide vane body are equipped with double sealing rings.

◆ Surface hardening treatment to extend service life. When pumping solid special media, the sealing ring can be rinsed with external water.

◆The product structure design is flexible and can be customized according to user requirements.
