Flex Flow
We Provide the Rental, Sale and Service of Horizontal Pump ("H-Pump") Solutions for fluid movement applications
Flex Flow (a DistributionNOW company) is a leading provider of H-pump solutions for surface applications across the energy industry. We offer rental, permanent installation, and service of high-performance horizontal pumping systems (HPS) and hydraulic jet pumps (HJP) and provide our customers with the H-pump expertise they need throughout the lifecycle of their water management applications. Let our proven, reliable solutions maximize production and lower your operating costs.

The Flex Flow System
The mobile HPS can be used to quickly deploy and support early project commissioning, increase operational capacity or replace failed equipment. It is designed to match flow rate and pressure requirements, the units can connect to existing control systems and are equipped with real-time remote monitoring to support safety shutdowns/alarms in compliance with regulatory requirements.
The HPS system is good for all types of fluid transfer. It is powered by electric motors that can be adjusted for speed. The pumps are multistage centrifugal pumps that can be used for high pressure or low- to medium-flow transfer and injection. The units can also be powered by existing facility electrical power or by a generator. Engineers have documented that this system has lower maintenance and repair costs, longer run life, and greater operating flexibility and efficiency.

Horizontal Pumping System
Flex Flow's trailer-mounted horizontal pumping system (HPS) is uniquely designed to provide fluid power for single or multiple jet pumps or SWD test pumps. This highly mobile HPS requires little maintenance and has a robust filtration system that prevents impurities from entering the pump or system. Service callouts are kept to a minimum, making Flex Flow an ideal solution for your fluid and water transfer needs.

Hydraulic Jet Pump
The Flex Flow hydraulic jet pump (HJP) is a better choice in challenging oilfield environments because it is efficient in vertical, deviated and horizontal wells. It also has excellent gas and solids handling and can be retrieved easily for maintenance. The advantages of HJP over conventional pumps can be determined with a NODAL analysis. This analysis shows that the HJPs have a quicker response time and enhanced accuracy.

Real-time Online Monitoring
The HJP and HPS can be monitored remotely to make adjustments that optimize system efficiency, including production and producing bottomhole pressure, as well as start/stop, speed change and troubleshooting. With digital cellular and satellite-enabled communications, the programmable logic controller (PLC) can report to tablets, mobile phones and computers with multiple notification options (email, text message and phone calls).
H-pump solutions that optimize completion, production and water management
Flex Flow Solutions - Innovative. Tested. Proven.
Flex Flow Services provides technology to lower risk and improve efficiency for completion, production and water management operations. The horizontal pumping system (HPS) can be used for optimizing water supply, injection, artificial lift, disposal, and distribution. The mobile, trailer-mounted system has a surface horizontal pumping system with variable speed drives, surface controls, and automated reporting capabilities. It is an excellent choice for all your fluid transfer applications with trailer-mounted or permanent installations.
HPS salt water disposal (SWD) solution
The HPS salt water disposal (SWD) system integrates a surface horizontal pumping system with variable speed drives, surface controls and automated reporting capabilities to lower the total cost of operations of saltwater disposal.
The HPS SWD system offers significant cost and performance advantages over conventional triplex positive displacement pumps with trailer-mounted or permanent installations. The HPS system uses field-proven multistage centrifugal pumps designed for high pressure, low- to medium-flow saltwater transfer and injection. Surface facilities engineers using these systems have documented lower maintenance and repair costs, longer run life and greater operating flexibility and efficiency.
The system offers the benefit of cost-effective rental options for temporary installs to provide testing for permanent equipment or to replace equipment under repair, and purchase options for permanent salt water disposal facilities are also available.


HPS water and fluid transfer solution
Our water and fluid transfer solution deploy a unique trailer-mounted or permanent horizontal pumping system that can be used to transfer water in a variety of production operations. The highly mobile HPS solution requires little maintenance, so service callouts are kept to a minimum. In addition, it has a robust filtration system that prevents impurities from entering the pump or the wellbore.
Ideal for all fluid transfer operations, the HPS system is engineered to match flow rate and pressure requirements. It is equipped with real-time remote monitoring to support safety shutdowns/alarms according to all regulatory requirements when connected to existing control systems.
Hydraulic jet pump (HJP) artificial lift solution
We offer operators artificial lift solutions from flow back through production with a unique horizontal pumping system (HPS) and versatile hydraulic jet pumps (HJP) that provide advantages over rod lift and ESP systems in many environments.
Our goal is to lift higher volumes and reduce operating costs by eliminating the common issues of artificial lift gas locking and solids handling, maintaining production over a wide range of rates and reducing well intervention and maintenance downtime.
For artificial lift operations, our solution combines a unique horizontal pumping system (HPS) with a versatile hydraulic jet pump (HJP) to provide many advantages over conventional artificial lift systems:
- Lower operating costs leading to reduced LOE
- Less maintenance with minimal downtime (98% to 100% run time)
- Highly mobile with a unique trailer-mounted system
- An efficient filtration system that prevents impurities from entering the pump and wellbore.
- Usage of a versatile downhole jet pump in conjunction with a gas lift and many completion scenarios (conventional, reverse circulation, and concentric).

The Flex Flow System has a successful track record
2018 case study shows how the Flex Flow System can add to the bottom line
Opportunity
An operator in Andrews, Texas, wanted a high-flow solution that would maximize well profitability.
Well specifications
- Casing 5 1/2 inches
- Tubing 2 7/8 inches
- TVD 6,680 ft
Equipment specifications
- Free-style standard-flow jet pump with an E:11 throat and nozzle
- 300-hp surface pumping unit
Success
The Flex Flow system, comprising a horizontal pumping system (HPS) and a hydraulic jet pump (HJP), proved to be a highly profitable artificial lift method. The incremental lifting cost was $24,000 or $11/bbl per month. With a net oil price of $45 and total monthly production of 2,088 bbl, the incremental monthly operating cash flow was $70,992.

2018 case study shows how the Flex Flow System can reduce OPEX/Interventions
Opportunity
In Andrews, Texas, an operator was plagued by high sand cut (1% to 3%), which caused a high failure rate in a well completed with an electrical submersible pump (ESP). The well was reconfigured to rod lift but failed 37 days after wearing out 115 tubing joints. The Flex Flow system was installed to reduce OPEX and the frequency of interventions.
Well specifications
- Casing 5 1/2 inches
- Tubing 2 7/8 inches
- TVD 9,500 ft
Success
The Flex Flow horizontal pumping system (HPS) and hydraulic jet pump (HJP) extended run life from ~38 days to 185 days, reducing OPEX/month by more than $25,000. Eliminating six interventions per year saved hundreds of thousands of dollars.

2018 case study shows how the Flex Flow System can achieve faster Frac flowback
Opportunity
An operator in Andrews, Texas, allowed Flex Flow to compare the performance of an electrical submersible pump (ESP) with a Flex Flow system comprising a horizontal pumping system (HPS) and a hydraulic jet pump (HJP). The test was run in two adjacent and similar wells after hydraulic fracturing and flowback. Well 1 was lifted with a Flex Flow system, and Well 2 was placed on an ESP.
Well specifications
- Casing 5 1/2 inches
- Tubing 2 7/8 inches
- TVD 10,000 ft
Success
The Flex Flow system consistently lifted higher volumes than the ESP during the first year of production. In addition, the Flex Flow system has a lower upfront cost than the ESP, making it the best choice for dewatering the well.
