Maintain Pump Efficiency and prevent costly downtime with reliable flow control

Pump protection

Protecting valuable pump equipment and ensuring optimal efficiency with minimal unplanned downtime is essential in any operation.

BT-Maric constant flow valves offer proven protection by maintaining consistent flow rate regardless of pressure variations – safeguarding pumps from damage caused by pressure instability, cavitation, or improper operation.
Designed to maintain a fixed, pre-set flow regardless of pressure differentials (within the range of 1.4–10 bar). BT-Maric constant flow valves ensure that there is always enough water available at the suction and that the pump always run not too far to the right of the best efficiency point. The installation of a BT-Maric Flow Control Valve provides pump protection by ensuring that flow rate can never exceed the manufacturer’s intended flow rate for the pump concerned.

Key Advantages for Pump Protection

1. Prevent Cavitation and Bearing Damage

Keep the pump operating on its performance curve, maintaining correct head pressure to avoid cavitation and mechanical wear.

2. Limit Peak Flow Rates

Regulate maximum flow to ensure water is efficiently drawn at the suction end – improving overall pump efficiency and avoiding pressure surges.

3. Protect Against System Overload and Pump Damage

Prevent over-pumping beyond bore capacity, which could otherwise cause air or sand ingress, pump instability, and up-thrust damage.

4. Ensure Compliance with Manufacturer Specifications Operation

By delivering a fixed, pre-set flow rate, BT-Maric valves maintain pump operation within design limits—minimizing wear, optimizing performance, and reducing the likelihood of warranty issues due to misuse or tampering.

5. Prevent unauthorised adjustments

By preventing unauthorised adjustments, BT-Maric flow valves ensure that the flow-rate can never exceed manufacturer’s intended rate.

6. Extend Lifespan of Pump Gland

Accurate flow control over gland flushing water significantly reduces wear, extending gland and packing lifespan and lowering maintenance frequency.

7. Reduce Water Consumption

Efficiently control water used for gland sealing—helping conserve valuable water resources without compromising pump protection.

8. Minimize Slurry or Product Dilution

By precisely managing gland water flow, the valves help maintain product integrity in slurry systems, avoiding unnecessary dilution.

Common Applications in Pump Protection

BT-Maric constant flow valves are widely used in applications where pump integrity and long-term reliability are critical:

• Cooling Systems for Liquid Ring Vacuum Pumps: Controls the cooling water flow to avoid electric motor overload.
• Borehole and Deep Well Pumping: Prevents up-thrust damage in high draw-down bores and stops over-pumping that could lead to suction of air or sediment.
• Slurry and Product Handling Systems: Limits dilution by precisely regulating gland water flow.
• Fixed-Flow Systems: Ensures flow rate never exceeds the manufacturer’s intended rate, maintaining system stability and equipment protection.

Built for Demanding Environments

BT-Maric Constant Flow Valves are engineered for durability and performance in harsh and variable conditions. A wide range of body materials and rubber insert options are available to match specific chemical or mechanical requirements.
