Closed Impeller Centrifugal Pump The Heart of Efficient Fluid Handling When it comes to moving liquids in various industrial and commercial applications, centrifugal pumps are the go-to solution due to their simplicity, reliability, and efficiency. Among the different types of centrifugal pumps, the closed impeller centrifugal pump stands out for its ability to handle a variety of fluids, its durability, and its operational efficiency. Whether you’re dealing with clean water, chemicals, or slurry, closed impeller centrifugal pumps are crucial in ensuring smooth fluid flow. In this blog, we’ll dive into what makes a closed impeller centrifugal pump unique, its key features, and why it’s a preferred choice for many industries.

Centrifugal Chemical Process Pump -FLP-OP Series Flow line Pumps FLP-OP Series Chemical process pump line is specifically designed to provide Highly Superior performance for low flow services of the Chemical Process Industrial Variable Applications. FLP-OP Series Chemical pumps are in various Materials of Construction with Semi Open Impellers as the construction of the pump for all Clear liquid or Slurry Type Liquid Handling in the Chemical Industries. FLP-OP Series can offer these pumps with various kinds of wear rings depending on the process liquids to serve its customers in a much better and efficient way providing them a pump which is free in maintenance Key Points about semi-open impellers: • Design: Has a back wall shroud that encloses the impeller vanes on one side, providing structural support while remaining open on the other side, allowing for fluid flow and solid passage. • Advantages: • Solid handling capability: Semi Open Impeller Can handle larger particles than a closed impeller without clogging as easily due to the open design. • Moderate efficiency: Offers better efficiency than a fully open impeller while still allowing for solid passage. • Versatility: Suitable for a wider range of fluid conditions with moderate solids content compared to a fully closed impeller. • Maintenance : Can be cleaned and inspected more easily than a fully closed impeller due to the partially open design. Operating Data: Head Range : 90 MT. Max. Pressure : 9 Bar Capacity : 250 m3/Hour Max. Pipe Line Size : 25 mm to 125 mm Sealing : PTFE Gland / Mechanical Seal Pump MOC : WCB/SS-304/SS-316/SS-316 L/Alloy20/Duplex Steel Impeller Type : Semi Open Connection Type: Flange Ended Speed Range : 2900 / 1450 RPM Features : 1. Back Pull Out Centrifugal Design 2. semi-open impellers with back vanes with anti-chocking Slurry. 3. Stuffing box options that allow for a variety of mechanical seals. 4. Design As per ANSI pump dimensions. 5. With smooth flow passages and larger eye area it helps in easy flow of slurries and solids content. Application: Distilleries (Fermentation and Evaporation Section) /Mineral Recovery Plants/ Speciality Chemicals / Pulp and Paper industry for the transfer of Black and Green Liquor. / Starch Industry / Dyes and Pigments /Chloro Alkali Plants / Pesticides and Insecticides /Fertilizers.

Vertical Inline Single Stage Centrifugal Pump Vertical Inline Single Stage FIL Series describing a specific type of pump manufactured by Flow Line Pumps, the FIL Series Vertical Inline Single Stage Pump. These pumps are designed for efficient circulation of liquids in heating and air-conditioning systems, offering several key features: 1. Vertical Inline Design: These pumps are compact and fit into a vertical installation, saving space and simplifying system integration. 2. Top Pull-Out Facility: This feature allows the removal of the stuffing box and impeller without having to disturb the casing or the suction/discharge pipework, making maintenance easier. 3. Drain at the Bottom: This drain feature helps in easy drainage and maintenance, preventing accumulation of liquids or contaminants in the pump casing. 4. Dynamically Balanced Impeller: By minimizing vibration, the balanced impeller helps improve the lifespan of bearings, enhancing the pump’s overall efficiency and reliability. Operating Data:  Head Range: 90 MT. Max.  Pressure: 9 Bar  Capacity: 250 m3/Hour Max.  Pipe Line Size: 25 mm to 250 mm  Sealing: Single Mechanical Seal Fitted  Pump MOC: Cast Iron/WCB/SS-304/SS-316  Impeller Type: Closed  Connection Type: Flange Ended Speed Range: 2900 RPM Features : Vertical inline long coupled through axially split rigid coupling  Suction and Delivery nozzles are cast integral with volute and are in-line. Impeller is enclosed type. It is dynamically balanced which ensures the smooth operation of the pump.  Volute is designed with smooth fluid flow passages Application: Water supply, HVAC, Air conditioning, Hot water up to 90°C, Drinking water Cooling water, Fire Fighting, Commercial Building Applications

Air-cooled Thermic Fluid Hot Oil Pumps is of horizontal, single-stage, single-suction volute type and has a closed impeller. Two robust ball bearings support the shaft to provide extra stability, giving the pump a hear-resistant Egleburgman Make mechanical seal. The suction flange is on the front and in the axial position, while the discharge flange is at the top in the radial position. FTP-AC Series of centrifugal pumps are specifically designed to handle thermal oils up to 350 Deg.C without the need of expensive mechanical seal and auxiliary cooling arrangements.
