SNP - diesel pump units (DPU) based on serial double-entry pumps 1D250-125 and specially designed pumps 1D 320-50-1. We significantly extended head range to 72- 115 m, and feed range to 130-330 m³/h.

Comparison chart of SNP-75/100 and equivalent DPU's:

Pumping units are primarily intended for agriculture, as well as for emergency power cutoffs, fire-fighting, jet method precious metals extraction and irrigation needs. The temperature of the pumped liquid is up to +95°C. Climatic class of U, UHL or T with location category 2 for U and T and 3.1 for UHL, operating temperature range from -45 to +40°C (depending on climatic class).

Diesel pumping units can be supplied in various frame design configurations. By request, the JSC “HMS Livgidromash” manufactures DPU's in:

·         standard frame version 

·         skid version 

·         wheelbase version.

Depending on version, the diesel pump unit  includes following: gas jet vacuum unit, manual valve, standard suction line, automatic start system, hood for protection against precipitation, liquid or electric prestart heater.

The Control System of Diesel Pump Unit is provided in two standard versions: 

·         manual control system 

·         microprocessor controller based automatic control system.

The Manual Control System of the diesel drive is equipped with a local control panel with function of diesel operation monitoring. The Alarm and Protection System (APS) provides alarm and engine trip in case of overheating and oil filter clogging. Diesel Pump Units with this Control System are intended for use in soil reclamation and  hydraulic engineering works.

Microprocessor controller based  Automatic Control System of diesel drive  provides control, protection and monitoring functions. Information about the engine status is displayed on the controller display and on the front panel mimic diagram. If necessary, additional parameters indication such as pump water pressure, pump bearing temperature and etc. is possible. All monitored parameters can be transferred to a personal computer. The control system has a built-in electric heater and a charger from an external 220V network, which allows to compensate the self-discharge of batteries when working in standby mode. This system is designed to control the Standby Pump, as well as in systems where automatic start and diesel drive operation control is required.

Each unit before shipment to the consumer are checked with specialized test rig providing unit's general functions testing. Thus, the products are delivered  with confirmation of all parameters declared to the Customer. The test rig is capable to check DPU in automatic mode by electronics. This allows to control and correct the necessary parameters while testing.
