North Ridge Pumps, the UK's largest pump supplier with over 25 years of industry expertise, has successfully engineered and delivered a specialized horizontal slurry pump solution for a major UK quarry operation, enabling the efficient transfer of highly abrasive 50/50 sand-water mixtures at unprecedented flow rates.
The client, a prominent UK quarry operator, approached North Ridge Pumps with a demanding requirement: to pump water with 50% sand content at flow rates exceeding 8 liters per second. This presented multiple engineering challenges due to the extreme abrasive nature of the mixture and the high-volume requirements.
Rather than offering an off-the-shelf solution, North Ridge Pumps' engineering team conducted a comprehensive assessment of the application requirements and designed a custom solution based on their XSP Series of rubber-lined heavy-duty slurry pumps.
The resulting pump incorporated several innovative features specifically engineered for this extreme application:
Comprehensive rubber protection: Unlike standard slurry pumps that typically feature only rubber-lined casings, North Ridge engineered both a rubber-coated impeller and rubber-coated volute to dramatically extend operational life in this highly abrasive environment.
Dual-protection sealing system: The pump features an expeller seal combined with a packed gland—an advanced configuration that eliminates leakage at low speeds and when the pump is stopped, while minimizing water consumption.
Adjustable clearance design: Recognizing that even the most durable rubber linings will eventually wear, the team incorporated front and rear adjustment capabilities, allowing operators to easily maintain optimal internal clearances throughout the pump's extended service life.
Material science excellence: The pump's casing was constructed from high-tensile ductile iron protected by a natural rubber liner, while the impeller received similar rubber protection against high-velocity abrasion. The shaft was manufactured from hardened AISI420 Stainless Steel for maximum durability.
This installation represents a significant advancement in slurry pumping technology for the quarrying and construction sectors. The ability to efficiently move sand slurry with such high solid content opens new possibilities for quarry operations looking to optimize their sand processing and transportation systems.
The implications of this pump technology extend well beyond sand processing. The same engineering principles and custom design approach can benefit industries ranging from metal processing and pulp/paper production to mining, dredging, and wastewater treatment.
