Overview

Product Overview

Product Description

SP Series Diesel Pump – Self-Priming, Portable, Off-Grid Operation

Built-in vacuum priming system enables suction lift up to 6m without foot valve. Diesel engine drive (11-120kW) – independent of electrical grid. Oil-lubricated mechanical seal handles dirty water. Heavy-duty cast iron casing with large discharge clearing capacity. Available on wheeled trailer for rapid deployment. Ideal for emergency and remote sites.

KEY FEATURES

  • Self-Priming Capability: Built-in priming system draws suction lift up to 6m without foot valve – starts quickly, no manual filling required.
  • Diesel Engine Driven: Independence from electrical grid ensures operation during power outages and in remote areas. Engine power from 11kW to 120kW.
  • Rapid Deployment Options: Available on heavy-duty wheeled trailer or skid base – ready for emergency response and mobile pump stations.
  • Oil-Lubricated Mechanical Seal: Reliable sealing for dirty sewage with solids, reducing maintenance compared to packing seals.
  • Large Solids Passage: Open or semi-open impeller options handle stringy solids and debris common in municipal and industrial wastewater.

Frequently Asked Questions

Why choose a diesel-driven self-priming pump instead of an electric submersible pump for sewage?
Diesel-driven pumps operate completely independently of the electrical grid. This is critical during floods (where power is often cut), in remote areas with no electricity, or for mobile emergency response. They also do not require submergence for cooling, can run dry for short periods, and are easier to inspect above ground.
What is the maximum suction lift the SP pump can achieve without priming?
The SP series can achieve a static suction lift of up to 6 meters (approximately 20 feet) using its built-in self-priming system. The priming time depends on the suction pipe length and diameter but is typically under 2-3 minutes. No external vacuum pump or foot valve is required.
What kind of solids or debris can this pump handle?
The SP series is designed for raw sewage and industrial wastewater. With an open or semi-open impeller, it can handle soft solids up to 50-80mm in diameter (depending on model) and fibrous materials like rags, string, and plastic film. For heavy sludge with large hard solids, please consult our engineering team.
Can the pump run continuously for extended periods (e.g., 24/7 during a flood event)?
Yes. The SP series is built for continuous heavy-duty operation. The diesel engine is rated for 100% continuous duty at rated power. The oil-lubricated mechanical seal and heavy-duty bearings are designed for extended run times. We recommend following the engine manufacturer’s maintenance schedule for oil and filter changes.
Do you supply the pump as a complete mobile unit with trailer and hoses?
Absolutely. We can supply the SP series as a complete “pump-in-a-box” mobile unit including: diesel engine pump, steel or aluminum suction/discharge hoses, fuel tank, battery, control panel, and heavy-duty trailer with road lighting and braking system (compliant with local road regulations). Please specify your deployment requirements for a turnkey quote.
