Product Description

LMV311 High Speed API Centrifugal Pump Vertical Integrally Geared Pumps

The LMV311 High-Speed Vertical Centrifugal Pump is the ideal solution for vertical pumping applications. For 18 years, Sunstrand Fluid Handling has been dedicated to precision pumping solutions for difficult and critical applications.

Our LMV311 series is a vertical, integral gear-driven high-speed centrifugal pump, specifically designed for low-flow, high-head duties in oil & gas, petrochemical, and chemical industries. Leveraging nearly two decades of application experience, we deliver not only API 610 (OH6) compliant hardware but also optimized fluid handling solutions derived from thousands of real-world cases.

Core Features

1. Industry-Leading Manufacturing Experience (18 Years)

Over the past 18 years, Sunstrand Fluid Handling has delivered more than 20,000 centrifugal pump systems worldwide. We understand the specific demands of various process fluids - from LPG to highly corrosive chemical intermediates - regarding mechanical seals and wetted parts. This application knowledge is the foundation of our product reliability.

2. Full API 610 Compliance

Every LMV311 is manufactured in a controlled environment. The integral speed-increasing gearbox is precision-ground to ensure low vibration levels and extended bearing life at high rotational speeds, fully meeting API 610 requirements for heavy-duty services.

3. Optimized Hydraulic Design (Low NPSHr)

For low suction pressure or high-vacuum conditions, Sunstrand offers a high-performance inducer option. Combined with our 18 years of CFD experience, this inducer effectively reduces the Net Positive Suction Head required (NPSH3) by more than 50%, preventing performance loss due to cavitation.

Typical Applications

Leveraging 18 years of delivery experience, the LMV311 is active in the following key process services:

Petroleum Refining: High-pressure recycle in hydrocrackers, vacuum tower overhead reflux.
Natural Gas Processing: Amine circulation in molecular sieve dehydrators, LNG unloading and peak-shaving.
Fine Chemicals: Continuous feed to high-pressure catalytic reactors, high-pressure recovery of expensive solvents.
Fertilizers & Agrochemicals: Carbamate solution circulation, high-pressure ammonia injection.
Power Generation & Boilers: Small high-pressure boiler feedwater, hot-well circulation make-up.
Polysilicon / High-Purity: High-purity chemical transfer and cryogenic circulation.

Frequently Asked Questions

Q1: What is the main advantage of the LMV311 over conventional multistage centrifugal pumps?

The main advantages are simplicity and footprint efficiency. By using an integral gearbox for single-stage high-speed operation, the LMV311 achieves the same head that would require multiple stages in a conventional pump. This results in a footprint reduction of over 50% and significantly fewer wearing parts (e.g., bearings and seals), leading to lower maintenance costs.

Q2: How does Sunstrand ensure high-speed reliability of the LMV311?

Reliability comes from our 18 years of manufacturing expertise. We apply precision dynamic balancing to the high-speed rotor train and use heavy-duty bearings compliant with API 610. Furthermore, every pump undergoes full vibration spectrum analysis prior to shipment, ensuring vibration levels well below industry standards at rated speed.

Q3: Can the LMV311 handle fluids with small amounts of solid particles?

The LMV311 is primarily designed for clean fluids. However, for special services, Sunstrand offers multiple hardened material options (e.g., tungsten carbide coating) and special mechanical seal flush plans (e.g., API Plan 32 or 53). We recommend providing the fluid composition during selection. Our engineers will match the best solution based on our 20,000-unit delivery database.

Q4: What solution do you offer for low NPSHa conditions?

We offer a dedicated inducer option. By optimizing the pressure distribution at the impeller eye, the NPSHr can be reduced to a very low level, effectively preventing cavitation and extending pump life.
