Technical Specifications

Performance Overview

The DPK range covers a comprehensive performance envelope:

The performance curve demonstrates the DPK series’ ability to handle demanding drainage applications requiring both significant flow capacity and high discharge heads—a combination that sets this range apart from standard drainage pumps.

Key Features & Benefits

High-Pressure Capability The DPK range delivers exceptional pressure performance relative to its compact size. This makes it suitable for deep drainage pits and applications requiring water to be lifted significant heights to reach discharge points.

Solid Cast Iron Construction Robust cast iron pump housing provides durability and long service life in demanding drainage environments. The solid construction withstands the rigors of continuous operation in wet well applications.

Highly Efficient Ductile Cast Iron Impeller The ductile cast iron impeller maintains its performance characteristics throughout extended operation, ensuring consistent hydraulic efficiency and increased service lifetime compared to standard materials.

Double Mechanical Shaft Seal Positioned within the oil chamber, the double mechanical seal system ensures trouble-free operation by providing reliable separation between the pumped liquid and motor components.

Easy Maintenance Oil Plug The accessible oil inspection plug enables quick assessment of seal chamber oil condition, allowing planned maintenance scheduling and proactive service before seal degradation affects pump operation.

Built-In Motor Protection The integrated bi-metal sensor protects against motor overheating, automatically responding to thermal conditions that could damage windings and ensuring extended motor lifetime.

Installation Flexibility

The DPK range offers versatile installation options to suit different site requirements:

Auto-Coupling with Guide Rails Submerged installation using auto-coupling systems enables pump removal for service without entering the wet well. Guide rails ensure proper pump alignment and secure connection to discharge piping.

Ring Stand (Freestanding) Portable configuration with ring stand base for applications requiring flexibility. Suitable for temporary installations or locations where fixed mounting is impractical.

Connection Options Pumps can be ordered with either flange or flexible hose connections depending on application requirements and site conditions.

Applications

The DPK range ensures quality, cost-effective drainage across diverse applications:

Building Services Underground drainage pits in commercial and residential buildings where the combination of high pressure capability and compact motor size matches space constraints while delivering required performance.

Courts Drainage Sports courts, parking structures, and outdoor facilities requiring reliable rainwater and groundwater removal with high-pressure discharge capability.

Industrial Applications Process water collection from various industrial functions where drainage pits collect water for onward pumping to treatment or discharge points.

General Surface Water Drainage Removal of rainwater and groundwater accumulation in basements, excavations, and below-grade structures.

Effective Drainage Solutions

The DPK range addresses drainage challenges where standard pumps fall short:

Deep Drainage Pits High head capability enables water removal from deep sumps where significant lift is required to reach discharge level.

Space-Constrained Installations Compact design relative to pressure capability allows installation in tight spaces while maintaining required performance.

Service Accessibility Design features including the oil inspection plug and flexible installation options simplify maintenance access and reduce service time.

Reliability Requirements Double mechanical seals and motor protection ensure dependable operation in critical drainage applications where pump failure causes flooding or operational disruption.
