Diesel-driven pump units of DNA type are intended for pumping of water and other liquids with the viscosity properties and chemical activity similar to water, namely, up to 36 10-6 m²/s (36sSt), with a temperature ranging from 274 up to 358К (from 1 up to 85°С), with the dry solids content not more than 0,05% by weight, with the size not more than 0,2 mm and misrohardness not exceeding 6,5 GPа (650kgf/mm²).
The units may be used in fire extinguishing systems.
The units are related to the items of aspect 1 (repairable) as per GOST 27.003-90 and are fabricated in climatic version UHL location category 3.1 as per GOST 15150-69. At the Client's request the units may be fabricated in another climatic version and location category.
The units are not intended for use in explosion and fire hazardous premises.
Stationary unit version comprises: the pump and diesel drive mounted on the frame.
The diesel drive consists of a power-generating set, which is served by motor switchbox (for the pumps having a frequency of rotation of 2900 rpm) or by power take-off (MOM) (for the pumps having a frequency of rotation of 1500 rpm).
Diesel drive is equipped :
The pump is attached to the frame of diesel drive. The pump is connected to the power-generating set by cardan shaft.
Sense of rotor rotation is right hand (clockwise), if viewed from the diesel drive end.
The system of manual control and SAPSiZ (warning protection system) of the unit comply with the 1 st automation degree as per GOST 14228-80 and activate the following functions: startup, control, automatic maintenance of revolutions, recharging of accumulators and emergency protection of diesel.

For example DNA-P-1D250/125а-GKLV UHL 3.1 TU 4734-306-05747979-2007, where :
Absence of any letter in the conventional designation means absence of a corresponding completing element in the delivery complete set. For example, the conventional designation of stationary unit version in a complex with the pump 1D250/125а without gas-jet vacuum device, without a hood, without winch and lifting mechanism, without suction line will be as follows: DNA-1D250/125a UHL 3.1 TU4734-306-05747979-2007
