Vertical turbine pumps (VTPs) are used in numerous industries, including power generation, pulp and paper, mining, and water and wastewater. The shafts on these pumps extend many feet under the ground, sometimes as deep as 2,000 feet.

Because of this and the often harsh and remote conditions in which they operate, these pumps must be reliable. For them to be reliable, the bushings and seal technology installed in them must survive for long periods.

According to a June 2018 Pumps & Systems article by the Electrical Apparatus Service Association (EASA), “The removal and reinstallation expenses for VTPs can be significant for long-set pumps that must be disassembled and reassembled on-site. Proper repair engineering, techniques and attention to dimensional integrity pay dividends in extended operational life for the machine.”

This article will examine the operating and maintenance challenges of VTPs and how users can solve them with a combination of technology for prolonged pump life.

Operations often begin in dry-run conditions, which potentially overheat and damage traditional bushings and seals. There is a need for assets that can withstand this short-lived but harsh operation. In addition, dirt, rocks and other debris may be lifted with the water. This causes wear and damage to the shaft and/or the bushing if the bushing material is ineffective.

Another issue is shaft deflection or “the bending of a pump shaft that occurs when the velocity of liquid being pushed by an impeller is not equal at all points around the impeller.”1 This deflection causes premature packing or mechanical seal wear. It also results in flush water leakage and difficulty in controlling the flush water usage.

To mitigate problems with wear, leakage and premature component failure, shaft stabilization is required. Also, selecting a seal technology that can withstand deflection will improve stuffing box/seal chamber reliability.

Shaft deflection, damaged bushing and damaged seals are problems when using VTPs. The first step for reliable operations is stabilizing the shaft with bushings. Some bushings can stabilize shafts in:

Sealing challenges travel hand in hand with maintenance challenges. Dirt, grit and rocks will move into the seal chamber/stuffing box with the liquid. To mitigate damage to the seal, proper flushing and cooling is required. In many VTP applications, clean water may be the best lubricant. However, end users and maintenance professionals should consult with the seal manufacturer.

Specialized barrier fluid may be required to maintain seal health, remove particulates, and properly cool the stuffing box or seal chamber. Shaft deflection can cause wear issues within the stuffing box or seal chamber as well. While the bushings minimize deflection, end users should select a seal that can tolerate some movement and the potentially abrasive environment.

A cartridge seal with high radial clearances is ideal for VTPs. A cartridge seal that is completely self-contained, preassembled and preset before shipping simplifies installation. These features also support quick and easy impeller adjustments that do not interfere with the correct axial setting of the seal.

The seal’s life depends on choosing the most effective materials of construction and its operating environment. This environment includes how clean the seal chamber/stuffing box is, and how cool the faces are.

For a seal installed on a VTP, a vented gland eliminates air entrapment and improves cooling efficiency. Machined glands offer superior corrosion resistance and strength and can be modified to fit

Each seal should be customized for each application (Image 4). For example, if packing had been used but the seal is now being placed in the stuffing box, the seal will need to fit. If a seal chamber is in place, then the seal will be different.

The Berkeley BVM15-5-300 is a non-self-priming/gravity feed, industrial pump with high pressure and low output. Often called a jockey pump, it is an ideal pump for a wide variety of pumping applications; water supply, pressure boosting systems, water treatment and filtration, irrigation, high pressure washes, liquid transfer, firefighting systems, boiler feed, condensate return, booster service and many more.

This cartridge grundfos mechanical seal is a smart design pump seal for grundfos vertical pump, this seal suit for grundfos CR CRI and CRN series vertical water pumps. As a special cartridge mechanical seal, we follow the original grundfos design 100% for this seal, this help to avoid any installation mistake when you install the seal for the grundfos pump, and make installation easy. Our grundfos mechanical seal frame and spring are made by strong quality stainless steel SS304( SS316 available too) material, help to against rusty problem. We use SSIC (Pressureless Sintered Silicon Carbide) as stationary and rotary seal face, it is much better than normal material RSIC(Reaction sintered Silicon Carbide), offer more wear resistance for the grundfos mechanical seal. For Rubber part, normally people choose EPDM or VITON for secondary seal. Our grunfos mechanical seal will make your pump as good as new and reduce downtime, and last longer time when pump running.
