G Series High-temperature Print and Dye Pump

1. Beyond Equipment Supply – A Solution for Complex Operating Conditions

In industries such as metallurgy, petrochemicals, food processing, papermaking, shipbuilding, nuclear energy, and mining, pumping reliability directly determines production uptime, maintenance costs, and operational safety.

Conventional centrifugal pumps often fail when faced with abrasive slurries, high-viscosity pastes, gas-entrained fluids, or corrosive chemicals – leading to cavitation, seal leakage, rapid wear, and unplanned downtime.

Jiangsu Rongsheng Import and Export Co., Ltd. – backed by over a decade of deep expertise in thermal engineering and solid-liquid two-phase flow handling from our parent company's lead oxide production equipment business – brings this industrial wisdom to fluid conveyance. Our Progressive Cavity Pump (PCP) is not a mass-produced standard unit. It is a custom-engineered positive displacement solution specifically designed for non-Newtonian fluids, high solid content, aggressive media, and extreme viscosity ranges.

2. Working Principle: The "Constant-Volume" Transfer via Dynamic Sealing

Unlike centrifugal pumps that rely on high-speed impeller rotation to impart kinetic energy, the progressive cavity pump operates on the internal rotary positive displacement principle:

• Core Assembly: A single-helix metallic rotor (manufactured from high-wear-resistant alloy) rotates inside a double-helix elastomeric stator (compounded with oil-resistant/acid-resistant rubber formulations).

• Kinematic Motion: The rotor, driven via a universal joint, performs a planetary (eccentric) motion within the stator cavity.

• Sealed Cavity Formation: The continuous meshing of the rotor and stator creates a series of progressive, sealed, equal-volume cavities along the axial length.

• Smooth Delivery: As these cavities move from the suction end to the discharge end, the medium is gently displaced – not sheared, not emulsified, not pulsed. Flow rate is strictly proportional to rotational speed, enabling precise metering.

3. Application Mapping: From "Moving Water" to "Conquering the Tough Media"

This pump series fundamentally eliminates the two fatal flaws of centrifugal pumps – cavitation and abrasion. Below is a direct mapping of your operational pain points to our engineered solutions:

4. Rongsheng Quality Standards: Beyond Parameter Sheets – Engineered for Durability

For continuous, mission-critical operations in petrochemical, nuclear, and marine sectors, we enforce three core manufacturing differentiators:

• Extended Service Life Technology: Our stators are compression-molded using high-elasticity, high-abrasion-resistant proprietary rubber compounds. Through finite element analysis (FEA), we optimize the interference fit between rotor and stator to minimize frictional heat generation, extending stator lifespan by 30%–50% compared to conventional designs.

• Precision Universal Joint Drive: We employ fully sealed, maintenance-free universal joints with hardened bearing surfaces. This ensures accurate rotor concentricity even under high eccentricity motion, eliminating stick-slip risks and achieving transmission efficiency up to 98%.

• Broad Viscosity Adaptability: By customizing rotor lead length and stator compression ratios, we tailor each pump to handle everything from low-viscosity water-like fluids to paste-like high-viscosity media – all within a single, reliable platform.
