ROTODEL Rotary Gear Pump – Type SPN / SP-II

The ROTODEL SPN / SP-II rotary gear pump is engineered with a robust and durable construction, featuring a uniquely optimized design for high performance and reliability.

The pump utilizes single helical impeller gears, precision-cut using a hob, and mounted on a hardened carbon steel shaft. This shaft is supported by heavy-duty ball bearings, which are housed within a machined casing and mounted on a wear-resistant plate.

The front cover incorporates a stuffing box equipped with either an oil seal or mechanical seals, ensuring effective sealing and minimal leakage. The rear cover includes a well-designed, integrated pressure relief valve for enhanced operational safety.

The pump is fitted with horizontally oriented BSP inlet and outlet ports, facilitating easy installation and efficient fluid flow.

Why Choose Rotodel?

End users in industries like petrochemicals, paints, lubricants, sugar, and food processing often choose Rotodel rotary gear pumps. These pumps are known for their ability to handle thick fluids, abrasive slurries, and corrosive chemicals. They provide reliable performance in various applications.

The pumps are engineered with precisely machined gear profiles and minimal clearances, ensuring volumetric efficiency and reduced slip even at higher pressures.

With options in cast iron, stainless steel, and alloy steel construction, Rotodel pumps provide compatibility with a wide range of media, from heavy fuel oils and bitumen to molasses, glycerin, and edible oils, while maintaining steady flow rates across varying viscosities.

Additionally, Rotodel pumps are designed for rugged operating conditions where reliability and ease of service are critical.

Their compact positive displacement mechanism, combined with self-priming capability and bi-directional flow, makes them suitable for both transfer and circulation duties.

Compared to other brands, Rotodel offers a favorable balance of durability, cost-effectiveness, and spare part availability, with localized service support that minimizes downtime.

This strong design, along with flexible materials and different capacity options, makes Rotodel a smart and efficient choice. Users can rely on it for long-term use without losing performance quality.
