Check Valves

Check valves are essential flow-control devices that ensure fluids or gases move in only one direction, preventing reverse flow that could lead to contamination, pressure drops, or mechanical damage. They function automatically based on pressure differentials—opening when upstream pressure exceeds the cracking pressure and closing when flow reverses or drops. Designs vary based on application needs: spring-loaded inline valves close quickly and can be installed in any direction, swing check valves are widely used in water systems, and ball check valves are self-cleaning and ideal for wastewater. Other types like lift, Y-shape, foot, and sanitary check valves cater to specialized functions, such as minimizing turbulence or maintaining hygiene. Their reliability and versatility make them indispensable across sectors like water treatment, HVAC, oil and gas, and pharmaceuticals.

Flygt Flanged Ball Check Valve

Flygt Flanged Ball Check Valves are designed for sewage and wastewater applications, offering low friction loss, maintenance-free operation, and reduced total cost of ownership. With full port design for maximum flow and minimal head loss, they feature a self-centring EPDM-coated aluminium ball for reliable closure at low pressures. All models support 200 PSI and include top-entry access for easy inspection and cleaning, available in 2", 3", 4", and 6" sizes.

Float Switches

Float switches are level-detection devices used in fluid management systems to automate pump operation and trigger alarms based on liquid levels. They operate by detecting the vertical movement of a float, either along a stem or cable, and using magnetic fields to open or close a reed switch. The configuration may be normally open (NO) for high-level triggers or normally closed (NC) for low-level alerts. Stem-mounted types offer fixed-level control, while cable-suspended versions provide more flexibility for variable-depth applications. Commonly found in sump pumps, tanks, and chemical systems, float switches must be constructed with materials compatible with the liquid environment. Their simplicity, reliability, and passive operation make them a go-to solution for liquid-level control.

Flygt ENM-10 Non-Mercury Pump Control Float Switch

The Flygt ENM-10 Non-Mercury Pump Control Float Switch offers dependable and efficient fluid level control for water and wastewater systems. Available in 20', 40', or 65' cable lengths, it features a durable, waterproof teardrop-shaped casing that resists debris buildup and uses a tilt-activated SPDT mechanical switch for precise performance. Ideal for pump control or alarm activation in lift stations and sumps, the ENM-10 supports flexible installation and reliable operation with minimal maintenance, making it a smart choice for both municipal and industrial applications.

Pump Lifting Equipment

Pump lifting equipment comprises the tools and systems used to safely handle, install, or remove pumps, especially heavy or submersible types, during maintenance or deployment. This equipment includes components such as lifting chains, hooks, slings, spreader bars, and cranes or hoists, all designed to distribute weight evenly and reduce mechanical stress on both the pump and operators. Built-in lifting eyes or custom brackets are often part of the pump design for secure attachment. Selecting the right lifting gear depends on the pump’s size, site conditions, and safety requirements. Proper use of lifting equipment ensures not only efficient handling but also minimizes workplace injuries and prolongs pump lifespan by avoiding damage during movement.

Flygt 6200900 Submersible Pump Lifting Grip Eye

The Flygt 6200900 Submersible Pump Lifting Grip Eye is a heavy-duty lifting accessory made from wrought alloy steel, designed for safely removing submersible pumps from lift stations without confined entry. Also known as a grab link, it works exclusively with Flygt’s 9/32" galvanized pump lifting chain and supports up to 2,600 lbs. The Grip Eye attaches to an electric hoist cable and slides down a taut chain; once the chain is slackened, it grips securely, enabling pump removal. It is only warranted for use with Flygt’s specified chain.

FAQs

1. Why is cracking pressure important when selecting a check valve?

Cracking pressure is the minimum pressure required to open a check valve. Choosing a valve with the appropriate cracking pressure ensures efficient flow initiation without causing unnecessary resistance or energy loss, especially in low-pressure or gravity-fed systems.

2. What makes cable float switches suitable for variable-depth level control?

Cable float switches are highly flexible and ideal for deep or irregular tanks. They can be positioned at custom activation points by adjusting the cable length, providing accurate level detection and pump control across a wide range of water levels.

3. How do float switches reduce the risk of pump burnout?

Float switches prevent pumps from running dry by shutting them off when liquid levels are too low, and they can also prevent overflow by stopping pumps when tanks are full. This automatic control helps protect the motor from damage, extending pump life.

4. How does the Flygt Grip Eye make submersible pump removal safer?

The Flygt Grip Eye attaches to a lifting hoist and slides along Flygt’s galvanized chain to securely grip and lift submersible pumps without entering the lift station. This tool eliminates confined space entry, reducing risks and simplifying maintenance.

5. What should you consider when choosing lifting gear for pump maintenance?

When selecting lifting gear, consider the pump's weight, mounting configuration, space constraints, and frequency of maintenance. Using purpose-built tools like lifting chains, spreader bars, and lifting eyes ensures safe handling, prevents equipment damage, and protects maintenance personnel from injury.
